Well, I'll spew some information and you can tell me if this is what you were asking…
The help server has the ability to overlay the contents of multiple directory trees. In the default configuration ($HFS/houdini/config/deploy.ini) that includes all HOUDINIPATH/help directories (that's what the special “@path” token does in the “docs =” line of the config file).
So, if you want to add a page at the root level of the help server, you could e.g. create “$HOME/houdiniX.X/help/mypage.txt”. Instructions on the wiki format the docs use is in the “How to use the help” chapter of the help. You could then view your page in the embedded browser at
http://localhost:48626/mypage.html. [localhost]
The tricky part is building the index. Since the configuration file that ships with Houdini depends on being run from inside Houdini (or at least hython – it imports hou for several things like getting the houdini path and pulling help out of digital assets), you'll probably need to get the stand-alone thing working before you try re-indexing using the script above.
In the list of directories on the “docs =” line of the configuration, later entries override earlier ones (the opposite of the Houdini path :twisted: ). So if e.g. you've got a standalone server setup where the original docs are in “/A” and your docs are in “/B” (and your config file says “docs = /A, /B”), you can override an original doc under “/A” by recreating the same path under “/B”, e.g. “/B/nodes/sop/copy.txt”.
Does that help?
