So, barring this, I'm curious how other people handle this issue.
I have multiple projects. Call them A, B, C. They are in directories:
Say I'm creating a new project, D, in ~/projects/D that uses code that
I've written in packages A, B and C. Now, as far as I can see, I have
1) Copy all the .(l)hs files from /A, /B, and /C to /D that I need to
2) Include projects/A, projects/B and projects/C in my search path for
I hate both of these options. 1 is terrible because I have multiple
copies of the same code lying around and, if I make changes to one, I
have to remember to copy the changes over to the others. 2 is a big
nuisance, especially since ghc (seems to) lack an environment variable
that it looks at to get command line options every time it runs
(HUGSFLAGS, I think it was for Hugs).
So is there a third option that I'm missing? How do other people handle
