[Eug-lug] Shell scripts to export environment variables?

[Mike Cherba]

instead of invoking the script with #!/bin/bash try using "source
scriptname" to run it within the current shell.  the #!/binbash
invokation spawns a subshell to run the script and the returns, blowing
away any environment variables you might have set.
