gruntmaster-exec - Gruntmaster 6000 executor

=head1 SYNOPSIS

  gruntmaster-exec 20000000 111 echo 'Hello, world!'

=head1 DESCRIPTION

gruntmaster-exec is the script used by gruntmasterd to run programs.

The first argument is the address space limit (in bytes), the second argument is the output limit (also in bytes). The rest of the arguments are the command that should be run and its arguments.

gruntmaster-exec sets the resource limits, cleans the environment (except for PATH and HOME), adds the ONLINE_JUDGE environment variable with value 1, and finally C<exec>s the given command.
