Bug#679950: compressor

[Marco van de Voort <marcov@pascalprogramming.org>]

I'm not that deep into debian packaging issues but:

the helpfile compiler is a single binary file (chmcmd) without any 
dependencies (not even libc). The resulting package would in general 
even be debian cross-version. It should be enough to extract the binary 
from the relevant FPC package and put it in its own, needing only update 
on FPC version changes.  So very low rundepends. (excuse my FreeBSD speak)

It should not become a drag on FPC upgrade ability though, so maybe some 
decoupling of the resulting package from the current FPC version would 
be nice.

The builddepends is essentially the same as the cumulative build 
dependencies of the fpc-chm package (fpc starting compiler, nearly 
entire FPC source archive, mostly built in one big go).

The CHM package is not entirely portable, it won't work on architectures 
that raise exceptions on misalignment (like ARM). Some simple testing 
was done with bigendian (powerpc) systems and that seemed to mostly 
work, but I expect a closer inspection to reveal minor bugs.
