# Path stuff.  This accounts for, at least:
#
#   - a custom Firefox install
#   - some bin dirs in my homedir
#   - golang
#
# Beware that other modifications to path might be made in .zshrc or .bashrc
# - and that _probably_ this should live somewhere that sets the environment for
# the entire X session.  It's a tangled mess which certainly warrants a TODO.
