 417
 418  Options:
 419    --debug             force debug mode (SQL Trace)
 420    --verbose           force verbose mode
 421    --help              display this help and exits
 422    --man               displays man page
 423    --tar=cmd           command to use for tar
 424    --directory=dir     dir to package
 425    --no-lzip           do not create .tar.lz files
 426    --delete            Delete packaging directory at start
 427
 428 =head1 OPTIONS
 429
 430 =over 4
 431
 432 =item B<--debug>
 433
 434 Forces debug mode cause all SQL statements generated by L<DBIx::Class>
 435 to be output.
 436
 437 =item B<--tar>
 438
 439 Use to override the path to the tar command; without this, will search for
 440 gtar, and if not found use tar.  Need GNU tar for lzip, unless --no-lzip is
