Usage: $ME [OPTION...] VERSION RELEASE_TYPE
-Run this script to perform the final pre-release NEWS update
-in which the date, release-type and version string are recorded.
-Commit that result with a log entry marking the release, and apply
-a signed tag. Run it from your project's top-level directory.
+Run this script from top_srcdir to perform the final pre-release NEWS
+update in which the date, release-type and version string are
+recorded. Commit that result with a log entry marking the release,
+and apply a signed tag. Run it from your project's top-level
+directory.
Requirements:
- you use git for version-control
-- a NEWS file, with line 3 identical to this:
-* Noteworthy changes in release ?.? (????-??-??) [?]
- a version-controlled .prev-version file
+- a NEWS file, with line 3 identical to this:
+$noteworthy_stub
Options:
- --branch BRANCH set release branch (default: master)
- --help print this help, then exit
- --version print version number, then exit
+ --branch=BRANCH set release branch (default: $branch)
+ -C, --builddir=DIR location of (configured) Makefile (default: $builddir)
+ --help print this help, then exit
+ --version print version number, then exit
EXAMPLE:
To update NEWS and tag the beta 8.1 release of coreutils, I would run this:
Report bugs and patches to <bug-gnulib@gnu.org>.
