It depends on which language you're writing the AGI script in.

In perl, it's @ARGV.  In C, it's the *argv[] you typically use
as an argument list for "main".

Note that in reality, the "path to the script itself" being
given by Asterisk isn't really true.  It happens that argv[0] in C
does give the line it was invoked with, but in perl that isn't
the case.

Refer to your favorite computer language's reference for a discussion
of UNIX command-line argument handling.
