   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...
