xit: a git alternative written in Zig

From the README:

You're looking at xit, a new version control system. Here be dragons, as they say. This is new and unstable software. Maybe one day it will be a worthy successor to git, but for now, only use it if you're adventurous. Here are the main features:

• git compatible
  • supports the git networking protocol for push/fetch/clone
  • read more about git compatibility
• combine snapshot-based and patch-based version control
  • merging and cherry-picking uses patches like Darcs and Pijul
  • restoring files and anything sent over the network uses snapshots like git
  • read more about snapshots vs patches
• built-in TUI
  • all functionality will be exposed via the TUI
  • for now though, it only shows log and status...baby steps!
  • read more about the TUI
• store large/binary files efficiently
  • uses a modern chunking algorithm (FastCDC) to deltify large files
  • doesn't compress binary files...it has no benefit and can even make them larger
  • read more about chunking
• universal undo
  • any change to the repo can be cleanly undone
  • this feature is still under development, so it's not available yet
  • read more about the immutable database
• clean implementation
  • uses no third-party libraries in production...all bugs are our bugs
  • can be easily used as a library in other projects
  • contains a reuseable git implementation in pure Zig
  • read more about xit's internals and using xit as a library
