Man pages are generated from the source markdown files (in md/) via the Makefile.
This uses ronn to generate the roff format man files e.g. ronn -r file.md
You can view the markdown files as formatted man pages via ronn --man file.md
Note: the source markdown files are first processed by a script to conditionally include/exclude BeyondTrust AD Bridge Enterprise only sections, and then by a second script to add troff paragraph indentation codes.
The supported format is specified in ronn-format and ronn covers the use of ronn itself.
