#    1) .bashrc is the *non-login* config for bash, run in scripts and after
#        first connection.
#
#    2) .bash_profile is the *login* config for bash, launched upon first
#        connection (in Ubuntu)
#
#    3) .bash_profile imports .bashrc in our script, but not vice versa.
#
#    4) .bashrc imports .bashrc_custom in our script, which can be used to
#        override variables specified here.
