pandoc/Setup.hs
John MacFarlane 79764df2d5 Added pandoc.1 to repository. Don't build as part of cabal build.
The process was too fragile.  It made too many assumptions about
available libraries (which failed sometimes when sandboxes were
used).  This is a low-tech solution.  The only drawback is that
`man/pandoc.1` is a generated file in the repository.  It will need
to be regenerated periodically when README changes.
