ops - phpMan

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 irreversible global effect, it
    is only of significant practical use with the "-M" option on the command
    line.

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