Have a low overhead, non timeconsuming way to get:

- package presence and version
- cflags and ldflags needed to properly link to the package
- checks for optional deps that may or may not trigger different behaviors.

- using package specific foo-config giving in various ways the same 
informations.
- using custom m4 macros to give the very same informations using 
various tricks
- every time redo the various compile&run you may find in the custom m4 
and/or trying random egrep on headers.

all of them are more time consuming than just having pkg-config and have 
just to produce a .pc file for your library...
