NAME

     ops - Perl pragma to restrict unsafe operations when
     compiling

SYNOPSIS

       perl -Mops=:default ...    # only allow reasonably safe operations

       perl -M-ops=system ...     # disable the 'system' opcode

DESCRIPTION

     Since the ops pragma currently has an irreversable global
     effect, it is only of significant practical use with the -M
     option on the command line.

     See the the Opcode manpage module for information about
     opcodes, optags, opmasks and important information about
     safety.
