+# This utility maintains the database for cscope on a recursive dir set
+# Author: donwo Tue Jun 25 15:36:39 PDT 1996
+# Modified: hops Jan 2000 chg defaults to not update if files exist and force
+#
+# These comments ARE the manual. What more do you really need?
+# if using unadorned cscope with this use cscope -d so not trash db
+# cscope -L -0 <ptn> - to display ptn matches on stdout
+#
+# The lists of files are kept in two forms:
+# TMP cscope.tmplst
+# The list generated by this program
+# This list will be updated each time this program
+# is executed.
+#
+# LST cscope.lst
+# The fixed list generated by some other process
+# This list will be used, if found, rather than
+# the TMP form generated here.
+#
+# CSD cscope.csd
+# The fixed list generated by some other process
+# This list will be used, if found, rather than
+# the LST or TMP forms. CSD differs from LST in
+# that the CSD list is used where the source files
+# change only seldom. Cscope is requested not to
+# check for changed files. This can be
+# significantly faster on large source trees.
+#
+# INC cscope.inc
+# This is a list of additional directories
+# in which to search for include files.
+#
+# Three hierarchies of libraries are supported:
+# Local In the current directory ./
+# This is most useful for transient projects or
+# where the information is of no use to others on
+# the system. This type is NOT usable on source
+# directories that are read-only.
+# Home In users home directory $HOME/lib/cs/`pwd`
+# This is good for items that seldom change but are
+# of use only the the current user. This type is
+# usable on source directories that are read-only.
+# System In a global system directory $SYSDIR/`pwd`
+# This is for items that are of interest to all accounts.
+# This option is not available unless the system directory
+# is writable by the current user. This type is usable
+# on source directories that are read-only.
+#
+# If a shell script named ./cscope.rc is found and is
+# executable, the execution of it will be included within this
+# script after defaults_set/cmdline_parse and locating the
+# database.
+#
+# Command line options:
+# -x set shell debugging
+# -f force
+# o Do not ask about regenerating TMP. Just do it.
+# o Allow cscope to regenerate libraries for CSD lists.
+# -q Tell cscope to build an inverted index for quick
+# symbol searching. There is a SIGNIFICANT
+# increase in speed with this option however the
+# disk space used is doubled. Once the quick
+# database is generated, cs will detect the files
+# and continue to use them.
+# -d Do not regenerate. Intended for cscope sub-tasks.
+# -u Update/regenerate.

+WebCScope Installation
+
+Quick Install
+
+0. Create a directory called cscope under your /cgi-bin (virtual) directory.
+ Copy all the files in the distribution to this directory.
+
+1. Edit the 'cscope' file and change the following items:
+ - Location to the perl interpreter
+ - Location of the cscope database and other modifiable parameters
+ - Feedback name and email
+ - Location of the syntax highlighter, if you wish to use it
+
+2. Syntax highlighter
+ - The syntax highlighter must be built if you decide to use it. If you
+ do not want syntax highlighting, you can ignore this step and set the
+ highlighter to /bin/cat.
+ - Compile 'hilite.c' using 'gcc -o hilite hilite.c'
+
+3. Icons
+ - Copy the images from the icons directory into the /icons (virtual)
+ directory on the web server. You can also replace these images with
+ whatever you choose.
+
+4. Organizing your CScope databases
+ - WebCScope supports multiple databases in $cscopedir
+ - Create a directory for each project or sub-source in $cscopedir and,
+ generate your cscope database using the following commands.
+ - find /some/source/dir -name '*.[chyls]' -print > cscope.files
+ - cscope -b -q
+ - Repeat the above step for each database you wish to create

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+ # header and body. Iterate between searching for these
+ # Retain a buffer of size(bufsize+maxbound); the latter part is
+ # to ensure that dividers don't get lost by wrapping between two bufs
+ # Look for a divider in the current batch. If not found, then
+ # save all of bufsize, move the maxbound extra buffer to the front of
+ # the buffer, and read in a new bufsize bytes. If a divider is found,
+ # save everything up to the divider. Then empty the buffer of everything
+ # up to the end of the divider. Refill buffer to bufsize+maxbound
+ # Note slightly odd organization. Code before BODY: really goes with
+ # code following HEAD:, but is put first to 'pre-fill' buffers. BODY:
+ # is placed before HEAD: because we first need to discard any 'preface,'
+ # which would be analagous to a body without a preceeding head.

+ Converts C (C++) source to HTML code fragment

+ Usage: CTHM <input_file>. All output is done

+ For HTML fragment generation:

+# Description: Script to index files for cscope
+#
+# This script generates a list of files to index
+# (cscope.out), which is then (optionally) used to
+# generate a cscope database. You can use this script
+# to just build a list of files, or it can be used to
+# build a list and database. This script is not used to
+# just build a database (skipping the list of files
+# step), as this can be simply done by just calling
+# "cscope -b".
+#
+# Normally, cscope will do its own indexing, but this
+# script can be used to force indexing. This is useful
+# if you need to recurse into subdirectories, or have
+# many files to index (you can run this script from a
+# cron job, during the night). It is especially useful
+# for large projects, which can contstantly have source
+# files added and deleted; by using this script, the
+# changing sources files are automatically handled.
+#
+# Currently, any paths containing "/CVS/" or "/RCS/" are
+# stripped out (ignored).
+#
+# This script is written to use only basic shell features, as
+# not all shells have advanced features.

+;; the cscope databases. If all of your source files are in one
+;; directory, you don't need this script; it's very nice to have,
+;; though, as it handles recursive subdirectory indexing, and can be
+;; used in a nightly or weekly cron job to index very large source
+;; repositories. See the beginning of the file, "cscope-indexer", for
+;; usage information.
+;;
+;; Installation steps:
+;;
+;; 0. (It is, of course, assumed that cscope is already properly
+;; installed on the current system.)
+;;
+;; 1. Install the "cscope-indexer" script into some convenient
+;; directory in $PATH. The only real constraint is that (X)Emacs
+;; must be able to find and execute it. You may also have to edit
+;; the value of PATH in the script, although this is unlikely; the
+;; majority of people should be able to use the script, "as-is".
+;;
+;; 2. Make sure that the "cscope-indexer" script is executable. In
+;; particular, if you had to ftp this file, it is probably no
+;; longer executable.
+;;
+;; 3. Put this emacs-lisp file somewhere where (X)Emacs can find it. It
+;; basically has to be in some directory listed in "load-path".
+;;
+;; 4. Edit your ~/.emacs file to add the line:
+;;
+;; (require 'xcscope)
+;;
+;; 5. If you intend to use xcscope.el often you can optionally edit your
+;; ~/.emacs file to add keybindings that reduce the number of keystrokes
+;; required. For example, the following will add "C-f#" keybindings, which
+;; are easier to type than the usual "C-c s" prefixed keybindings. Note
+;; that specifying "global-map" instead of "cscope:map" makes the
+;; keybindings available in all buffers:
+;;
+;; (define-key global-map [(control f3)] 'cscope-set-initial-directory)
+;; (define-key global-map [(control f4)] 'cscope-unset-initial-directory)
+;; (define-key global-map [(control f5)] 'cscope-find-this-symbol)
+;; (define-key global-map [(control f6)] 'cscope-find-global-definition)
+;; (define-key global-map [(control f7)]
+;; 'cscope-find-global-definition-no-prompting)
+;; (define-key global-map [(control f8)] 'cscope-pop-mark)
+;; (define-key global-map [(control f9)] 'cscope-next-symbol)
+;; (define-key global-map [(control f10)] 'cscope-next-file)
+;; (define-key global-map [(control f11)] 'cscope-prev-symbol)
+;; (define-key global-map [(control f12)] 'cscope-prev-file)
+;; (define-key global-map [(meta f9)] 'cscope-display-buffer)
+;; (defin-ekey global-map [(meta f10)] 'cscope-display-buffer-toggle)
+;;
+;; 6. Restart (X)Emacs. That's it.

+;;
+;; ***** USING THIS MODULE *****
+;;
+;; * Basic usage:
+;;
+;; If all of your C/C++/lex/yacc source files are in the same
+;; directory, you can just start using this module. If your files are
+;; spread out over multiple directories, see "Advanced usage", below.
+;;
+;; Just edit a source file, and use the pull-down or pop-up (button 3)
+;; menus to select one of:
+;;
+;; Find symbol
+;; Find global definition
+;; Find called functions
+;; Find functions calling a function
+;; Find text string
+;; Find egrep pattern
+;; Find a file
+;; Find files #including a file
+;;
+;; The cscope database will be automatically created in the same
+;; directory as the source files (assuming that you've never used
+;; cscope before), and a buffer will pop-up displaying the results.
+;; You can then use button 2 (the middle button) on the mouse to edit
+;; the selected file, or you can move the text cursor over a selection
+;; and press [Enter].
+;;
+;; Hopefully, the interface should be fairly intuitive.
+;;
+;;
+;; * Locating the cscope databases:
+;;
+;; This module will first use the variable, `cscope-database-regexps',
+;; to search for a suitable database directory. If a database location
+;; cannot be found using this variable then a search is begun at the
+;; variable, `cscope-initial-directory', if set, or the current
+;; directory otherwise. If the directory is not a cscope database
+;; directory then the directory's parent, parent's parent, etc. is
+;; searched until a cscope database directory is found, or the root
+;; directory is reached. If the root directory is reached, the current
+;; directory will be used.
+;;
+;; A cscope database directory is one in which EITHER a cscope database
+;; file (e.g., "cscope.out") OR a cscope file list (e.g.,
+;; "cscope.files") exists. If only "cscope.files" exists, the
+;; corresponding "cscope.out" will be automatically created by cscope
+;; when a search is done. By default, the cscope database file is called
+;; "cscope.out", but this can be changed (on a global basis) via the
+;; variable, `cscope-database-file'. There is limited support for cscope
+;; databases that are named differently than that given by
+;; `cscope-database-file', using the variable, `cscope-database-regexps'.
+;;
+;; Note that the variable, `cscope-database-regexps', is generally not
+;; needed, as the normal hierarchical database search is sufficient
+;; for placing and/or locating the cscope databases. However, there
+;; may be cases where it makes sense to place the cscope databases
+;; away from where the source files are kept; in this case, this
+;; variable is used to determine the mapping. One use for this
+;; variable is when you want to share the database file with other
+;; users; in this case, the database may be located in a directory
+;; separate from the source files.
+;;
+;; Setting the variable, `cscope-initial-directory', is useful when a
+;; search is to be expanded by specifying a cscope database directory
+;; that is a parent of the directory that this module would otherwise
+;; use. For example, consider a project that contains the following
+;; cscope database directories:
+;;
+;; /users/jdoe/sources
+;; /users/jdoe/sources/proj1
+;; /users/jdoe/sources/proj2
+;;
+;; If a search is initiated from a .c file in /users/jdoe/sources/proj1
+;; then (assuming the variable, `cscope-database-regexps', is not set)
+;; /users/jdoe/sources/proj1 will be used as the cscope data base directory.
+;; Only matches in files in /users/jdoe/sources/proj1 will be found. This
+;; can be remedied by typing "C-c s a" and then "M-del" to remove single
+;; path element in order to use a cscope database directory of
+;; /users/jdoe/sources. Normal searching can be restored by typing "C-c s A".
+;;
+;;
+;; * Keybindings:
+;;
+;; All keybindings use the "C-c s" prefix, but are usable only while
+;; editing a source file, or in the cscope results buffer:
+;;
+;; C-c s s Find symbol.
+;; C-c s d Find global definition.
+;; C-c s g Find global definition (alternate binding).
+;; C-c s G Find global definition without prompting.
+;; C-c s c Find functions calling a function.
+;; C-c s C Find called functions (list functions called
+;; from a function).
+;; C-c s t Find text string.
+;; C-c s e Find egrep pattern.
+;; C-c s f Find a file.
+;; C-c s i Find files #including a file.
+;;
+;; These pertain to navigation through the search results:
+;;
+;; C-c s b Display *cscope* buffer.
+;; C-c s B Auto display *cscope* buffer toggle.
+;; C-c s n Next symbol.
+;; C-c s N Next file.
+;; C-c s p Previous symbol.
+;; C-c s P Previous file.
+;; C-c s u Pop mark.
+;;
+;; These pertain to setting and unsetting the variable,
+;; `cscope-initial-directory', (location searched for the cscope database
+;; directory):
+;;
+;; C-c s a Set initial directory.
+;; C-c s A Unset initial directory.
+;;
+;; These pertain to cscope database maintenance:
+;;
+;; C-c s L Create list of files to index.
+;; C-c s I Create list and index.
+;; C-c s E Edit list of files to index.
+;; C-c s W Locate this buffer's cscope directory
+;; ("W" --> "where").
+;; C-c s S Locate this buffer's cscope directory.
+;; (alternate binding: "S" --> "show").
+;; C-c s T Locate this buffer's cscope directory.
+;; (alternate binding: "T" --> "tell").
+;; C-c s D Dired this buffer's directory.
+;;
+;;
+;; * Advanced usage:
+;;
+;; If the source files are spread out over multiple directories,
+;; you've got a few choices:
+;;
+;; [ NOTE: you will need to have the script, "cscope-indexer",
+;; properly installed in order for the following to work. ]
+;;
+;; 1. If all of the directories exist below a common directory
+;; (without any extraneous, unrelated subdirectories), you can tell
+;; this module to place the cscope database into the top-level,
+;; common directory. This assumes that you do not have any cscope
+;; databases in any of the subdirectories. If you do, you should
+;; delete them; otherwise, they will take precedence over the
+;; top-level database.
+;;
+;; If you do have cscope databases in any subdirectory, the
+;; following instructions may not work right.
+;;
+;; It's pretty easy to tell this module to use a top-level, common
+;; directory:
+;;
+;; a. Make sure that the menu pick, "Cscope/Index recursively", is
+;; checked (the default value).
+;;
+;; b. Select the menu pick, "Cscope/Create list and index", and
+;; specify the top-level directory. This will run the script,
+;; "cscope-indexer", in the background, so you can do other
+;; things if indexing takes a long time. A list of files to
+;; index will be created in "cscope.files", and the cscope
+;; database will be created in "cscope.out".
+;;
+;; Once this has been done, you can then use the menu picks
+;; (described in "Basic usage", above) to search for symbols.
+;;
+;; Note, however, that, if you add or delete source files, you'll
+;; have to either rebuild the database using the above procedure,
+;; or edit the file, "cscope.files" to add/delete the names of the
+;; source files. To edit this file, you can use the menu pick,
+;; "Cscope/Edit list of files to index".
+;;
+;;
+;; 2. If most of the files exist below a common directory, but a few
+;; are outside, you can use the menu pick, "Cscope/Create list of
+;; files to index", and specify the top-level directory. Make sure
+;; that "Cscope/Index recursively", is checked before you do so,
+;; though. You can then edit the list of files to index using the
+;; menu pick, "Cscope/Edit list of files to index". Just edit the
+;; list to include any additional source files not already listed.
+;;
+;; Once you've created, edited, and saved the list, you can then
+;; use the menu picks described under "Basic usage", above, to
+;; search for symbols. The first time you search, you will have to
+;; wait a while for cscope to fully index the source files, though.
+;; If you have a lot of source files, you may want to manually run
+;; cscope to build the database:
+;;
+;; cd top-level-directory # or wherever
+;; rm -f cscope.out # not always necessary
+;; cscope -b
+;;
+;;
+;; 3. If the source files are scattered in many different, unrelated
+;; places, you'll have to manually create cscope.files and put a
+;; list of all pathnames into it. Then build the database using:
+;;
+;; cd some-directory # wherever cscope.files exists
+;; rm -f cscope.out # not always necessary
+;; cscope -b
+;;
+;; Next, read the documentation for the variable,
+;; "cscope-database-regexps", and set it appropriately, such that
+;; the above-created cscope database will be referenced when you
+;; edit a related source file.
+;;
+;; Once this has been done, you can then use the menu picks
+;; described under "Basic usage", above, to search for symbols.
+;;
+;;
+;; * Interesting configuration variables:
+;;
+;; "cscope-truncate-lines"
+;; This is the value of `truncate-lines' to use in cscope
+;; buffers; the default is the current setting of
+;; `truncate-lines'. This variable exists because it can be
+;; easier to read cscope buffers with truncated lines, while
+;; other buffers do not have truncated lines.
+;;
+;; "cscope-use-relative-paths"
+;; If non-nil, use relative paths when creating the list of files
+;; to index. The path is relative to the directory in which the
+;; cscope database will be created. If nil, absolute paths will
+;; be used. Absolute paths are good if you plan on moving the
+;; database to some other directory (if you do so, you'll
+;; probably also have to modify `cscope-database-regexps').
+;; Absolute paths may also be good if you share the database file
+;; with other users (you'll probably want to specify some
+;; automounted network path for this).
+;;
+;; "cscope-index-recursively"
+;; If non-nil, index files in the current directory and all
+;; subdirectories. If nil, only files in the current directory
+;; are indexed. This variable is only used when creating the
+;; list of files to index, or when creating the list of files and
+;; the corresponding cscope database.
+;;
+;; "cscope-name-line-width"
+;; The width of the combined "function name:line number" field in
+;; the cscope results buffer. If negative, the field is
+;; left-justified.
+;;
+;; "cscope-do-not-update-database"
+;; If non-nil, never check and/or update the cscope database when
+;; searching. Beware of setting this to non-nil, as this will
+;; disable automatic database creation, updating, and
+;; maintenance.
+;;
+;; "cscope-display-cscope-buffer"
+;; If non-nil, display the *cscope* buffer after each search
+;; (default). This variable can be set in order to reduce the
+;; number of keystrokes required to navigate through the matches.
+;;
+;; "cscope-database-regexps"
+;; List to force directory-to-cscope-database mappings.
+;; This is a list of `(REGEXP DBLIST [ DBLIST ... ])', where:
+;;
+;; REGEXP is a regular expression matched against the current buffer's
+;; current directory. The current buffer is typically some source file,
+;; and you're probably searching for some symbol in or related to this
+;; file. Basically, this regexp is used to relate the current directory
+;; to a cscope database. You need to start REGEXP with "^" if you want
+;; to match from the beginning of the current directory.
+;;
+;; DBLIST is a list that contains one or more of:
+;;
+;; ( DBDIR )
+;; ( DBDIR ( OPTIONS ) )
+;; ( t )
+;; t
+;;
+;; Here, DBDIR is a directory (or a file) that contains a cscope
+;; database. If DBDIR is a directory, then it is expected that the
+;; cscope database, if present, has the filename given by the variable,
+;; `cscope-database-file'; if DBDIR is a file, then DBDIR is the path
+;; name to a cscope database file (which does not have to be the same as
+;; that given by `cscope-database-file'). If only DBDIR is specified,
+;; then that cscope database will be searched without any additional
+;; cscope command-line options. If OPTIONS is given, then OPTIONS is a
+;; list of strings, where each string is a separate cscope command-line
+;; option.
+;;
+;; In the case of "( t )", this specifies that the search is to use the
+;; normal hierarchical database search. This option is used to
+;; explicitly search using the hierarchical database search either before
+;; or after other cscope database directories.
+;;
+;; If "t" is specified (not inside a list), this tells the searching
+;; mechanism to stop searching if a match has been found (at the point
+;; where "t" is encountered). This is useful for those projects that
+;; consist of many subprojects. You can specify the most-used
+;; subprojects first, followed by a "t", and then followed by a master
+;; cscope database directory that covers all subprojects. This will
+;; cause the most-used subprojects to be searched first (hopefully
+;; quickly), and the search will then stop if a match was found. If not,
+;; the search will continue using the master cscope database directory.
+;;
+;; Here, `cscope-database-regexps' is generally not used, as the normal
+;; hierarchical database search is sufficient for placing and/or locating
+;; the cscope databases. However, there may be cases where it makes
+;; sense to place the cscope databases away from where the source files
+;; are kept; in this case, this variable is used to determine the
+;; mapping.
+;;
+;; This module searches for the cscope databases by first using this
+;; variable; if a database location cannot be found using this variable,
+;; then the current directory is searched, then the parent, then the
+;; parent's parent, until a cscope database directory is found, or the
+;; root directory is reached. If the root directory is reached, the
+;; current directory will be used.
+;;
+;; A cscope database directory is one in which EITHER a cscope database
+;; file (e.g., "cscope.out") OR a cscope file list (e.g.,
+;; "cscope.files") exists. If only "cscope.files" exists, the

+;; variable, `cscope-database-file'. There is limited support for cscope
+;; databases that are named differently than that given by
+;; `cscope-database-file', using the variable, `cscope-database-regexps'.
+;;
+;; Here is an example of `cscope-database-regexps':
+;;
+;; (setq cscope-database-regexps
+;; '(
+;; ( "^/users/jdoe/sources/proj1"
+;; ( t )
+;; ( "/users/jdoe/sources/proj2")

+;; )
+;; ( "^/users/jdoe/sources/gnome/"
+;; ( "/master/gnome/database" ("-d") )
+;; )
+;; ))
+;;
+;; If the current buffer's directory matches the regexp,
+;; "^/users/jdoe/sources/proj1", then the following search will be
+;; done:
+;;
+;; 1. First, the normal hierarchical database search will be used to
+;; locate a cscope database.
+;;
+;; 2. Next, searches will be done using the cscope database
+;; directories, "/users/jdoe/sources/proj2",
+;; "/users/jdoe/sources/proj3/mycscope.out", and
+;; "/users/jdoe/sources/proj4". Note that, instead of the file,
+;; "cscope.out", the file, "mycscope.out", will be used in the
+;; directory "/users/jdoe/sources/proj3".
+;;
+;; 3. If a match was found, searching will stop.
+;;
+;; 4. If a match was not found, searching will be done using
+;; "/some/master/directory", and the command-line options "-d"
+;; and "-I/usr/local/include" will be passed to cscope.
+;;
+;; If the current buffer's directory matches the regexp,
+;; "^/users/jdoe/sources/gnome", then the following search will be
+;; done:
+;;
+;; The search will be done only using the directory,
+;; "/master/gnome/database". The "-d" option will be passed to
+;; cscope.
+;;
+;; If the current buffer's directory does not match any of the above
+;; regexps, then only the normal hierarchical database search will be
+;; done.
+;;
+;;
+;; * Other notes:
+;;
+;; 1. The script, "cscope-indexer", uses a sed command to determine
+;; what is and is not a C/C++/lex/yacc source file. It's idea of a
+;; source file may not correspond to yours.
+;;
+;; 2. This module is called, "xcscope", because someone else has
+;; already written a "cscope.el" (although it's quite old).
+;;
+;;
+;; * KNOWN BUGS:
+;;
+;; 1. Cannot handle whitespace in directory or file names.
+;;
+;; 2. By default, colored faces are used to display results. If you happen
+;; to use a black background, part of the results may be invisible
+;; (because the foreground color may be black, too). There are at least
+;; two solutions for this:
+;;
+;; 2a. Turn off colored faces, by setting `cscope-use-face' to `nil',
+;; e.g.:
+;;
+;; (setq cscope-use-face nil)
+;;
+;; 2b. Explicitly set colors for the faces used by cscope. The faces
+;; are:
+;;
+;; cscope-file-face
+;; cscope-function-face
+;; cscope-line-number-face
+;; cscope-line-face
+;; cscope-mouse-face
+;;
+;; The face most likely to cause problems (e.g., black-on-black
+;; color) is `cscope-line-face'.
+;;
+;; 3. The support for cscope databases different from that specified by
+;; `cscope-database-file' is quirky. If the file does not exist, it
+;; will not be auto-created (unlike files names by
+;; `cscope-database-file'). You can manually force the file to be
+;; created by using touch(1) to create a zero-length file; the
+;; database will be created the next time a search is done.
