+hence DVI and Postscript), Groff, and plain text output from any

+Sometimes the dependencies get in the way: if you've made a small
+change to one file, and you're absolutely sure that it won't affect
+anything else, but you know that @make@ is going to rebuid everything
+anyway, the following hack may be useful:
+
+<tscreen> <verb>
+gmake FAST=YES
+</verb> </tscreen>
+
+This tells the make system to ignore dependencies and just build what
+you tell it to.  In other words, it's equivalent to temporarily
+removing the @.depend@ file in the current directory (where
+@mkdependHS@ and friends store their dependency information).
+
+A bit of history: GHC used to come with a @fastmake@ script that did
+the above job, but GNU make provides the features we need to do it
+without resorting to a script.  Also, we've found that fastmaking is
+less useful since the advent of GHC's recompilation checker (see the
+User's Guide section on "Separate Compilation").
