[Lazarus] authoring user manuals

[Gour]

Hello,

by looking at
http://wiki.lazarus.freepascal.org/Add_Help_to_Your_Application page it
seems there are several options to provide help (aka user manual) for
one’s app - CHM, HTML & INF.

Now I wonder which one is recommended and if there are some helpers
assisting manual authors to use some higher-level markup like
markdown/AsciiDoc/rst?


Sincerely,
Gour
