* Split lib/default.nix into several files, as it had become a big mess. Also cleaned up some functions: - foldl appeared broken (it recursively called fold). - Renamed logicalAND/logicalOR to and/or. - Removed listOfListsToAttrs, eqStrings: obsolete. - Removed isInList, which does the same thing as elem. - stringToCharacters: don't return a "" at the end of the list. - Renamed concatList to concat, as concatList (singular) is a misnomer: it takes two lists. Likewise, renamed mergeAttr to mergeAttrs. misc.nix still contains a lot of stuff that should be refactored and moved to other files. svn path=/nixpkgs/trunk/; revision=14013 2009-02-09 19:51:03 +03:00			`rec {`
