• Polyfill: functionality current systems implement natively.
• Prollyfill: functionality future systems expect to implement natively, as defined by widely accepted specifications.
• Nottifill: functionality future systems may implement natively, as desired by developers.
• Ponyfill: a strategy where functionality is implemented as an independent module.

# In order for gpg to find gpg-agent, gpg-agent must be running, and there must be an env
# variable pointing GPG to the gpg-agent socket. This little script, which must be sourced
# in your shell's init script (ie, .bash_profile, .zshrc, whatever), will either start
# gpg-agent or set up the GPG_AGENT_INFO variable if it's already running.

# Add the following to your shell init to set up gpg-agent automatically for every shell
