npm-completion.sh

#
# npm command completion script
#
# Install Method 1: Automatic
# Put this file in /etc/bash-completion.d or /usr/local/etc/bash-completion.d
# or wherever bash-completion scripts are sourced on your system.
#
# Install Method 2: Generic
# Put this in .bashrc or whatever file you run when you log into a machine:
# . path/to/npm-completion.sh
#
# Then use the tab key, which executes the "npm completion" command.
#
# Special thanks to Evan Meagher for making the npm completion command
# much more useful and complete.
