# Self-contained .bash_profile

# .bash_profile sourced at every login shell, and applies to the whole session.
#
# Its job is to set the path, run commands that should only be run once per 
# session such as keyrings, handle eveything required for the session and all 
# sub-shells.

# Test for an interactive shell.  There is no need to set anything
# past this point for scp and rcp, and it's important to refrain from
# outputting anything in those cases.
