Well, maybe policy is a too strong word. As I am a Makefile and autoconf idiot, I am a prime example of those copy and paste guys: I just use the same system, that Thomas uses in the flext-tutorials. (I would love to see an autoconf example for flext exernals. I will adapt it immediatly.)
Actually, i'm currently working out a new build system for the flext library and flext externals, based on central make includes (in the flext folder) and only small makefiles for the actual externals. I'll put it in the cvs soon. Since i don't have experiences with automake ot autoconf i'd appreciate any related support.
best greetings, Thomas
