In order for us to create an io_src file for an include the header must:
|
||||
|

1. Reside in a user directory ( not system dirs like /usr/include

2. Not reside in an excluded directory
|

3. Not have ICG: (No) present in the Trick header
|

If the header file meets all of these conditions, a PrintFileContentsBase

instance is created for that file name.
