Proposals: 1) New field extra-tmp-files, a list of extra files to be removed by setup clean, beyond those that can be deduced. 2) Rename other-files as extra-source-files for consistency and clarity. 3) New field data-files, a list of files to be copied to a place where an executable can find them (e.g. template-hsc.h for hsc2hs): Hugs: the directory containing the Main module GHC/Windows: the directory containing the executable GHC/Unix: /usr/local/share/<exename> plus a new function in System.Directory to return the name of this directory. That would address Dimitry's requirements in http://www.haskell.org/pipermail/haskell-cafe/2005-July/010886.html Dimitry has a more elaborate proposal: http://www.haskell.org/pipermail/libraries/2005-July/004146.html
