customizing index generation

[Stefan Seefeld <stefan@seefeld.name>]

Hello,

I'm writing an API reference manual for a library, whose symbols all
start with a common prefix. Having added one indexterm per symbol, the
generated index now contains a list with a single letter - the first
letter of the shared prefix.

So, having "foo_something" and "foo_other" would now generate a single
letter "F" under which both symbols are listed.

Is there a way to strip off the common prefix for purposes of index
generation only, that is without actually removing the prefix from the
indexed symbols themselves ?

So, The two symbols "foo_something" and "foo_other" above would end up
in two sections, the first under "S", the second under "O".

Is that possible ?

Thanks,
		Stefan
