libtool/clcommit.m4sh
Stepan Kasal 03590110e7 * clcommit.m4sh: "grep|sed" can be replaced by mere "sed". 
* m4/libtool.m4 (_LT_LIBTOOL_TAGS): Remove unnnecessary "[]".
* m4/lt~obsolete.m4: Use m4_ifndef.

# Usage: $progname [OPTION]... [--] [file|dir ...]
# -C FILE --changelog=file extract commit message from specified ChangeLog
# -zN --compress=N set compression level (0-9, 0=none, 9=max)
# --debug enable verbose shell tracing
# -n --dry-run don't commit anything
# --fast same as --force --first
# -F file --file=file read commit message from file
# -1 --first extract first entry from ChangeLog, no cvs diff
# -f --force don't check (unless *followed* by -n), and just
# display commit message instead of running $PAGER
# --from=addr override default from address in commit email
# -l --local don't descend into subdirectories
# -m msg --message=msg set commit message
# --msg=msg same as -m
# -r [FILE] --rcfile[=FILE] read default option from FILE [./.clcommitrc]
# -q --quiet run cvs in quiet mode
# -s addr --sendmail=addr send a commit email of the differences to ADDR
# --signature[=FILE] add FILE to the end of the email [~/.signature]
# -S TEXT --summary=TEXT specify a TEXT subject line for the commit email
# -t --tla use tla as the scm (and cvs in a dual tree)
# -v --verbose run in verbose mode
# --version print version information
# -h,-? --help print short or long help message
# This script eases checking in changes to CVS-maintained projects
# with ChangeLog files. It will check that there have been no
# conflicting commits in the CVS repository and print which files it
# is going to commit to stderr. A list of files to compare and to
# check in can be given in the command line. If it is not given, all
# files in the current directory (and below, unless `-l' is given) are
# considered for check in.
# The commit message will be extracted from the differences between a
# file named ChangeLog* in the commit list, or named after -C, and the
# one in the repository (unless a message was specified with `-m' or
# `-F'). An empty message is not accepted (but a blank line is). If
# the message is acceptable, it will be presented for verification
# (and possible edition) using the $PAGER environment variable (or
# `more', if it is not set, or `cat', if the `-f' switch is given).
# If $PAGER exits successfully, the modified files (at that moment)
# are checked in, unless `-n' was specified, in which case nothing is
# checked in.
