This is a little tool I made for all programmers who need to call SetFunction()
from C (or C++). It is intended to make life easier and to make source files more
readable.

Usually, when one want to use SetFunction(), he/she must look in .fd files or
#pragma statements to find the LVO of each function he/she want to patch (*). This
leads to source files difficult to understand and maintain, since each call to
SetFunction() looks like:

oldfunction=SetFunction(Execbase,-690,myfunction);

where you can't understand very well which function is being patched, unless you
add tons of comment lines to each call.

(*)= All the system libraries offsets exist through amiga.lib, but 3rd party
libraries don't. This is why I made FOCS!

FOCS (that stands for Function Offset Creator for SetFunction() ), takes a file
with LVOs and creates nice C header (.h) files, with a symbol definition for each
function found in the LVO file.
So the example above will look like:

oldfunction=SetFunction( Execbase, FOS_FreeVec, myfunction );

Nice, isn't it ?

FOCS version 1.0 support the following file formats:
 - SAS C #pragma files
 - StormC #pragma files (similar but not the same stuff).
 - FD files (those who started it all).
 - GCC inline's (hopefully... only the new, preprocessor based format is
   supported).
