create git repositories and include project info for cgit

README

  • This script will generate a bare git repo in your current user's ${HOME} directory
  • it will query you for relevant info that the frontend (cgit) will use and dispay to users
  • it will make an initial README.md commit to the repository
  • this is intended to be used with this project https://github.com/dweinstein/minimal-cgi-server-for-cgit
    • basically this hosts cgit (http://git.zx2c4.com/cgit/) from a minimal python http server so you don't have to go setup lighthttp or apache.
