# 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.
