I've been trying to get up to tricks with the in clause of uses, eg.
uses GHJStdDefs in 'GHJLibraries/GHJStdDefs.p' ;
It seems to me that the in clause only supports filenames, not paths - true? (or put another way, that's what it appears to do: is this the intended/standard/expected behaviour?) The only way I have been able to get GPC to see my libraries is to use --unit-path on the command-line. I'll pop a note into the doc forms later.
The reason I wanted to do the above was so I could place a soft link to the real library (etc.) directory in the working code directory, so that the library locations are effectively embedded in the code, yet are relative to the directory they are compiled from. Also, it means I can later point the link to new versions of the library and just recompile without altering anything else.
(Yes, I know I should really use make files...)
