# Running this will display a filterable list of modules
# Once you select one, you will navigate to it
# You can call it with an argument to be used as a pre-filter on the module list

# Requires 'fzf', I highly recommend it.
# https://github.com/junegunn/fzf
# In this case, 'fzf' is reading from stdin

# USAGE EXAMPLES
# gm              (will present the full list of modules)
