Subject: [PATCH] git-cvsimport-script: add "import only" option
X-Git-Tag: v0.99.1~60
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=c1c774e7965ba08061c3fc7bc57aebc7eeb6b40f;p=git.git

[PATCH] git-cvsimport-script: add "import only" option

git-cvsimport-script: add "import only" option which tells the script
not to perform a checkout after importing.

This ensures that the working directory and cache remain untouched and
will not create them if they do not exist.
