-- ;dev: Add a ghc-tags.yaml file (Jonathan Dowland)
-  Provide a ghc-tags.yaml file to make use of ghc-tags with Hledger easy.
-
-  ghc-tags is a standalone tool to replace the formerly-built-in
-  ":ctags" feature (and I presume ":etags") in GHCi. These walked over
-  the source and produced a TAGS file (in vim-compatible ctags or
-  Emacs-compatible etags format) that allows the relevant editors to
-  quickly navigate around function definitions.
-
-  ghc-tags trips over some of the CPP used in Hledger. The solution
-  is to provide ghc-tags with explicit CPP defines via a YAML file.
-  However, if a YAML file is provided, one also must specify the source
-  paths, as the tool XORs config file | paths-on-command-line.
