Thanks, but please also send this to git@vger.kernel.org. And please try do inline the patches, it makes it much easier to review; I've pasted the patches below and inserted a few comments prefixed with 'lh>'.

This is a temporary solution to creating archives from repos containing submodules. It will just create a series of archives, each named after the name of the submodule. --- git-submodule.sh | 87 +++++++++++++++++++++++++++++++++++++++++++++++++++++- 1 files changed, 86 insertions(+), 1 deletions(-)

Is this really common enough to justify a special option to `submodule init`? Maybe the .gitmodules file could be extended to contain multiple urls instead (i.e. both absolute and relative ones)? Then `submodule init` could get options like --prefer-relative-url, --prefer-absolute-url and --interactive. What do you think? -- larsh
