[aspectc-user] AC++ --aspect_header and -p problems

[Olaf Spinczyk]

Hi!

It is intended but (obviously) not sufficiently documented. The main 
reason for having a -p option is to distinguish between files ac++ is 
allowed to transform (project files) and files that must remain 
untouched (all the rest, e.h. system header files). As aspect headers 
have to be transformed, they have to be located in a directory tree, 
which is provides by a -p option. The -a option mainly disables the 
automatic search for all *.ah in the project.

Best regards,

Olaf
