2 * Catia VFS module
3 *
4 * Implement a fixed mapping of forbidden NT characters in filenames that are
5 * used a lot by the CAD package Catia.
6 *
7 * Yes, this a BAD BAD UGLY INCOMPLETE hack, but it helps quite some people
8 * out there. Catia V4 on AIX uses characters like "<*$ a *lot*, all forbidden
9 * under Windows...
