 If you change the Cabal description file of your project, you need to
 reconfigure it by calling ''Setup.lhs config'' (assuming that your Setup
 program is called ''Setup.lhs'').  Since most editors don't know anything
 about Cabal, that requires you to have a shell open and type the command
 in question manually, which can get quite annoying, if you reconfigure
 often.

 ''Setup.lhs build'' recognizes the case, when the configuration has
 changed and dies with an error.  It would be very useful, if it would call
 the ''configure'' command automatically instead, for example with the last
 used flags, or with a default set of flags configured in the description
 file.
