usage: nwbootstrap [options]

Exports a revision of the BitKeeper tree (nwbootstrap must be run inside a
directory of the BitKeeper tree to be used).  Creates the ChangeLog file.
Adds the latest manual.texi from the mysqldoc BitKeeper tree.  Builds the
Linux tools required for cross-platform builds.  Optionally, builds the 
binary distributions for NetWare.

options:

--build=<opt>               Build the binary distributions for NetWare,
                            where <opt> is "standard", "debug", or "all"
                            (default is to not build a binary distribution)
                            
--build-dir=<dir>           Export the BitKeeper tree to the <dir> directroy
                            (default is "$build_dir")
                            
--doc-dir=<dir>             Use the mysqldoc BitKeeper tree located in the
                            <dir> directory
                            (default is parallel to current BitKeeper tree)
                            
--help                      Show this help information

--revision=<rev>            Export the BitKeeper tree as of revision <rev>
                            (default is the latest revision)
                            
--wine-build-dir=<dir>      Use the WINE directory <dir>, which should
                            correspond to the --build-dir directory
                            (default is "$wine_build_dir")

examples:

  nwbootstrap

  nwbootstrap --revision=1.1594 --build=all
  
  nwbootstrap --build-dir=/home/jdoe/dev --wine-build-dir=F:/dev
