/*
|
|
experimental
|
|
idea:
|
|
a) Attach some information to a nexpression telling how to create a tag file which can then be used within your favourite editor
|
|
Do this in a way not affecting the expression (using passthru or meta which is ignored when calculating the hash)
|
|
implementations: addCTaggingInfo (C / C++) and addHasktagsTaggingInfo (Haskell)
|
|
b) use sourceWithTagsDerivation function to create a derivation installing the source along with the generated tag files
|
|
so that you can use them easily witihn your favourite text editor
