Bash-it provides support for enabling/disabling proxy settings for various shell tools.

The following backends are currently supported (in addition to the shell's environment variables): Git, SVN, npm, ssh

Bash-it uses the following variables to set the shell's proxy settings when you call 'enable-proxy'.
These variables are best defined in a custom script in bash-it's custom script folder ('$BASH_IT/custom'),
e.g. '$BASH_IT/custom/proxy.env.bash'
* BASH_IT_HTTP_PROXY and BASH_IT_HTTPS_PROXY: Define the proxy URL to be used, e.g. 'http://localhost:1234'
* BASH_IT_NO_PROXY: A comma-separated list of proxy exclusions, e.g. '127.0.0.1,localhost'

Run 'glossary proxy' to show the available proxy functions with a short description.
