Hello Jakub, I had some time to look through the perl module in the Git sources and I wanted to summarize the changes that need to be made -

[Primary Task] [1] Move exception handling from Error::Simple to Try::Tiny and Exception::Class

[Additional] [2] A Git::Config module that parses the .gitconfig file and the .git/config file in each repository(Is it one of these files or both?) [3] Parsing Tree and Commit objects and then traverse the tree structure in Perl through a Git::Commit module. [4] Cleaning-up improving the API. In general move towards an module that can access and change data in the configuration and commit status using Perl instead of the fork and IPC being used now.

Is this what you expect as a part of the GSoC work? Could you please tell me if I am missing something.

Cheers, Subho.
