Re: [PLUG] Determining when a shell script is sourced

[gary@duzan.org]

   If this is a concern, a better approach may be to have the script clean
up after itself so that nothing leaks into the shell that sources it.
In bash, at least, you can do things like "unset -f" to get rid of
functions, "type -t" to check for existing functions so you don't
replace them, etc.
