When installing fpc-ide I don't get any documentation. I think I should, really.
The fpc-ide documentation is part of the fpc documentation, which you can install by building fpc with the doc flag. Chapter 6 of the user manual covers the IDE. This is not available as a separate document, sorry.
After installing with
dev-lang/fpc-2.0.4 USE="doc -source"
I still see no documentation in the ide.
Here is the docs that are installed.
du -s /usr/doc/fpc-2.0.4/*
user.pdf is the user manual I mentioned.
