[jsword-devel] Module Installation

I got an answer to the module installation problem on sword-devel, now I 
just need to understand it!

I know from the mail below what the c++ code does to download modules, 
but I don't know c++ so I'm struggling. Can anyone help?

I was trying to understand where AbsoluteDataPath comes from and I came 
across this line:

for (; ((*buf2) && ((*buf2 == '.') || (*buf2 == '/') || (*buf2 == 
'\\'))); buf2++);

And my brain crashed.
I don't know perl either, but I'm betting that that line is also valid 
in perl, however in perl it is a complete implementation of the game of 
life or something.

It's probably not worth spending ages over because I reckon it must be 
possible to go from the module type + module name, but I any of you 
speak c++ like a native and could tell me from these sources, what to 
download I'd be grateful.

Hey Joe,
	Yeah, we have an attribute stored for a module called: AbsoluteDataPath
which will return the directory the fullpath to the datafiles.  It's
built in SWMgr.  There is duplicate code in src/mgr/installmgr.cpp that
does the same thing (which should be removed and used AbsoluteDataPath,
but give the algorithm more concisely).

	Hope this helps,

cf. /RawGenBook

cf.  /AbsoluteDataPath
