[Lazarus] Building help files: the nitty-gritty

[Mark Morgan Lloyd]

I normally build Lazarus from svn, targeting bigide, so I'm not sure 
that instructions that tell me to download prebuilt binary .chm files 
are relevant to me. However, if I could ask two questions here about the 
mechanics:

a)  Assuming that ChmHelpPkg is loaded but lhelp is not compiled. Since 
the new version of Lazarus might not yet have been run, is there an 
idiot-proof way of telling lazbuild what Lazarus directory etc. is to be 
used when building lhelp.lpi?

b)  What is the easiest way of integrating .chm files for the RTL etc., 
to the extent that context-sensitive help works for things like 
Format()? Again, if I'm building FPC from source I presume it makes more 
sense to generate these locally (unless it expects lots of Latex 
handling or equivalent).

Finally, if I just want to add a few lines of plain text as 
context-sensitive help for a control or form, with the main 
documentation having been prepared by e.g. Lyx and saved as a .pdf, 
what's the way to do this?
