## Name

remapid — reassign region idents in a BRL-CAD or TANKILL model according to commands in a specification file

## Synopsis

`remapid` [ - [ `g` | `t` ]] [ `file.g` | `file.tankill` ] [`spec_file`]

## DESCRIPTION

Performs batch modifications of region IDs for BRL-CAD (or TANKILL) geometry. The program reads a .g (or TANKILL) file and a spec file indicating which region IDs to change to which new values. For a .g file, the specified changes are made to that file; For a TANKILL file, a modified model is written to stdout. The remapping assignment is read from a specification file containing commands, the grammar for which looks something like:

command --> id_list ':' id
id_list --> id_block | id_block ',' id_list
id_block --> id | id '-' id
id --> [0-9]+

The semantics of a command is: For every region in the database whose region ID appears in the id_list before the ':', change its region ID to the value appearing after the ':'.
