Also added infrastructure to have developers write man pages in
Markdown (vs. nroff). Pandoc >=v1.12 is used to convert those
Markdown files into actual nroff man pages.
Dist tarballs will contain generated nroff man pages; we don't want to
require users to have Pandoc installed. Anyone who builds Open MPI
from a git clone will need to have Pandoc installed (similar to how we
treat Flex). You can opt out of Open MPI's Pandoc-generated man pages
by configuring Open MPI with --disable-man-pages. This will also
disable "make dist" (i.e., "make dist" will error if you configured
with --disable-man-pages).
Also removed the stuff to re-generate man pages.
This commit also:
1. Includes a new man page, written in Markdown
(ompi/mpi/man/man5/MPI_T.5.md) that contains Open MPI-specific
information about MPI_T.
2. Includes a converted ompi/mpi/man/man3/MPI_T_init_thread.3.md (from
MPI_T_init_thread.3in -- i.e., nroff) just to show that Markdown
can be used throughout the Open MPI code base for man pages.
3. Made the Makefiles in ompi/mpi/man/man?/ be full-fledged
Makefile.am's (vs. Makefile.extras that are designed to be included
in ompi/Makefile.am). It is more convenient to test generation /
installation of man pages when you can "make" and "make install" in
their respective directories (vs. doing a build / install for the
entire ompi project).
4. Removed logic from ompi/Makefile.am that re-generated man pages if
opal_config.h changes.
Other man pages -- hopefully all of them! -- will be converted to
Markdown over time.
