Doug Hellmann c7bfdbb44f split install guide into separate files by OS
Provide a script for interpreting the "only" directives and splitting
the existing content up into standalone files for each OS to make it
easier for project teams to copy the parts they need into their own
project documentation trees without requiring separate platform builds.

The files have been hand-edited to pass the niceness check and to allow
the install guide to build.

The script for building the guide has been changed to not build separate
copies per OS.
