## vcsh
# When you clone a remote repository foo, vcsh does the following behind the scene:
# 1. create a folder in .config/vcsh/repo.d/foo.git, and export it as GIT_DIR.
# 2. create $VCSH_BASE directory, i.e your home directory by default; and 
#    export it as GIT_WORK_TREE
# Thus the work tree and git meta data, aka .git folder, are separated. 
# We can use git fetch to pull the remote repository into the GIT_DIR, and 
# merge the changes back to the GIT_WORK_TREE.


# To see the current remote repository.
# "vcsh mr remote show origin"
# "vcsh mr remote remove origin"
# "vcsh mr remote add origin http://github.com/crazzyfool/mr.git"
# "vcsh mr push --set-upstream origin master"

# These can be aliased in the config file. See below

## mr
# To get started using mr, perhaps you already have some checked out repositories. Go into each one and run 


# "mr register". 

# Now mr has a list of them in ~/.mrconfig, which you can edit later to tune its operation.

# Suppose you've cd'd to ~/src, and it has many repositories under it. To update them all, run 

# "mr update".  
# "mr commit".  commit any pending changes
# "mr status". check the status of each,
# "mr push".  push changes to all repositories.
