I agree with you that need to do a storing on disk or to produce CHW.
And I will do this later.
Creating a new chm package additions also requires a lot of time.
But now I have not any documentation on chm format, I have found only
dribs and drabs.
The situation is such that the documentation seems an existing, but it
is very difficult to use for many reasons.
Actual version of lHelp has to work rightly and then I can do next
version. First start 1.5-2 sec I think it is well for loading entire
packet of chms and indexes.
