A service that provides an API for searching and comparing prices and deals on tickets, vehicle rentals, and suchlike.
A minimalist decentralized issue management system based on Git. No back-end, no dependencies. Tickets are stored in the same Git repo as the project as text files in the .issues/ directory. Added to the other Git commands as an alias. Aims to be cross-platform, actually works on pretty much any *nix-alike.
Uses git's internal storage so no files are added in your project. As you would do with commits and branches, you can push your bugs to the same git remote you are already using to collaborate with other people.
