You can hardly blame us for you not remembering things... :-)

Because the naming convention on unixes is like that for config files in
your home directory. This is not fpc specific.

This convention predates the systems used by desktop environments which nowadays puts
everything in ~/.config or ~/.share or some other convention. But it is
still in use today.

So, rather than adapting to the flavour of the day config system, we stick to
what - after all these years - is still common practice on unix, and which
we have been consistently using since day 1.

If you don't like this name, fine: you can set an environment variable to
point the compiler to where it is.


You only need to do this once.

So it's not like we don't offer you a myriad of ways to specify a config
