man: generate manpages from .org files

Generate the manpages from org-documents which makes it a bit easier to
keep them update to date since I find org-syntax easier than troff, and
we can use include files.

+* COMMON OPTIONS
+
+** -d, --debug
+makes mu generate extra debug information, useful for debugging the program
+itself. By default, debug information goes to the log file, ~/.cache/mu/mu.log.
+It can safely be deleted when mu is not running. When running with --debug
+option, the log file can grow rather quickly. See the note on logging below.
+
+** -q, --quiet
+causes mu not to output informational messages and progress information to
+standard output, but only to the log file. Error messages will still be sent to
+standard error. Note that mu index is much faster with --quiet, so it is
+recommended you use this option when using mu from scripts etc.
+
+** --log-stderr
+causes mu to not output log messages to standard error, in addition to sending
+them to the log file.
+
+** --nocolor
+do not use ANSI colors. The environment variable ~NO_COLOR~ can be used as an
+alternative to ~--nocolor~.
+
+** -V, --version
+prints mu version and copyright information.
+
+** -h, --help
+lists the various command line options.
