This isn't a Perl script. This is a shell script to be executed by
whichever shell lives at /usr/bin/sh on your system. It sets the shell
variables ORACLE_HOME and LD_LIBRARY PATH, and then calls /bin/perl to
re-evaluate the file. When the perl interpreter reads the file, it
ignores the shell statements. See perlrun for the gory details.
A less complex method would be to just set $ENV{ORACLE_HOME}, etc. in Perl.
