How to navigate around the source tree?

[Ömer Sinan Ağacan]

I use a file finder (fzf) for jumping to files. Because module names follow file
paths to jump to e.g. StgToCmmUtils.Utils I usually type `<C-p>stgcmmutils` and
fzf finds the correct file `compiler/GHC/StgToCmm/Utils.hs`.

When generating tags I omit module names for this reason, it's easy with a good
file finder to jump to modules already, no need to generate tags for the
modules.

fast-tags commands I use:

- When working on the compiler:

  $ fast-tags --no-module-tags driver ghc compiler

- When working on the RTS:

  $ fast-tags --no-module-tags driver ghc compiler
  $ ctags --append -R rts/**/*.c rts/**/*.h includes/**/*.h

- When working on the libraries:

  $ fast-tags --no-module-tags driver ghc compiler libraries
