Installing documentation involving several subdirectories

[Mayuresh <mayuresh%acm.org@localhost>]

A package's html documentation is very exhaustive and is contained in
several subdirectories in its docs directory.

The package does not have a makefile that would have installed the
documentation.

I find, install command doesn't have an option to copy the whole directory
tree. (Why?) How to deal with this? Simple wildcard won't work. I may have
to use find command. Any other simpler choice?
