# A simple bash script to share git repositories via standard git daemon application
# run: "git_serv start [--listen <address>]"     to start git daemon listening on address
# run: "git_serv share [repository_name]"        inside a repository to share this repository.
# run: "git_serv del_share"                      inside a repository to stop sharing this repository
# run: "git_serv stop"                           to stop serving 
#
# After first to steps your repository will be available to be cloned via command:
#     "git clone git://<address>/repository_name
#
# Notes:
#   - repository_name default is set to name of toplevel repository folder.
#   - <address> default is set to listen on address(domain) returned by command linux shell command `hostname`
