Subject: release-tools.sh: store the timestamp and release tag too
X-Git-Tag: curl-8_8_0~271
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fd6c16c345160a7728e0609788d76d36dcbb3fd7;p=thirdparty%2Fcurl.git

release-tools.sh: store the timestamp and release tag too

When maketgz invokes this script to generate the docs/RELEASE-TOOLS.md
file that gets bundled in the release, it now also passes on the exact
timestamp and version number so that those details also get mentioned in
the document. They will help users reproduce an identical tarball.

Closes #13319
