perl mode

[Gabriel C Millerd]

back in college when i evoked emacs on a non existant file such as
such as something.(pl|c|cpp|sh) it would have common text that would be
used to start such a file. such as #!/path/program and what not.

anyone direct me to where i can figure out how to do this for myself?
perferablly from my home directory and perferablly for perl mode?

thanks very much
