# SYNOPSIS
|
|
#
|
|
# AX_GENERATE_CHANGELOG()
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Builds a rule for generating a ChangeLog file from version control
|
|
# system commit messages. Currently, the only supported VCS is git, but
|
|
# support for others could be added in future.
|
|
#
|
|
# Defines GENERATE_CHANGELOG_RULES which should be substituted in your
|
|
# Makefile.
|
|
#
|
|
# Usage example:
|
|
#
|
|
# configure.ac:
|
|
#
|
|
# AX_GENERATE_CHANGELOG
|
|
#
|
|
# Makefile.am:
|
|
#
|
|
# @GENERATE_CHANGELOG_RULES@
|
|
# CHANGELOG_START = 0.2.3^
|
|
# dist-hook: dist-ChangeLog
|
|
#
|
|
# ChangeLog (stub committed to VCS):
|
|
#
|
|
# The ChangeLog is auto-generated when releasing.
|
|
# If you are seeing this, use 'git log' for a detailed list of changes.
|
|
#
|
|
# This results in a "dist-ChangeLog" rule being added to the Makefile.
|
|
# When run, "dist-ChangeLog" will generate a ChangeLog in the
|
|
# $(top_distdir), using $(CHANGELOG_GIT_FLAGS) to format the output from
|
|
# "git log" being run in $(CHANGELOG_GIT_DIR).
|
|
#
|
|
# Unless Automake is initialised with the 'foreign' option, a dummy
|
|
# ChangeLog file must be committed to VCS in $(top_srcdir), containing the
|
|
# text above (for example). It will be substituted by the automatically
|
|
# generated ChangeLog during "make dist".
