usage: tgStoreLoad -G <gkpStore> -T <tigStore> <v> [input.cns]

  -G <gkpStore>         Path to the gatekeeper store
  -T <tigStore> <v>     Path to the tigStore and version to add tigs to

  -L <file-of-files>    Load the tig(s) from files listed in 'file-of-files'

  -n                    Don't replace, just report what would have happened

  The primary operation is to replace tigs in the store with ones in a set of input files.
  The input files can be either supplied directly on the command line or listed in
  a text file (-L).

  A new store is created if one doesn't exist, otherwise, whatever tigs are there are
  replaced with those in the -R file.  If version 'v' doesn't exist, it is created.

  Even if -n is supplied, a new store is created if one doesn't exist.

  To add a new tig, give it a tig id of -1.  New tigs must be added to the latest version.
  To delete a tig, remove all children, and set the number of them to zero.
