Comment (by ryandesign):

 Replying to [comment:17 Dave-Allured]:
 > It looks like `openldap` and `wget` use the same troff/texinfo source
 format for man pages.  `wget` builds them with the lighter weight
 `texinfo` port.  Therefore I suggest seeing whether `texinfo` can be
 substituted for the `groff` dependency in `openldap`.

 I don't see any way for that to be possible. troff and texinfo are not the
 same format. Each format needs to be manipulated by tools that understand
 that format.

 wget distributes its documentation in texinfo (texi) format. Its build
 system uses `makeinfo` to convert the texinfo file to info format for use
 with the `info` command. `makeinfo` used to be included with macOS; on
 older macOS versions it will use the macOS copy of `makeinfo` if the
 texinfo port is not installed. wget's build also uses a bundled perl
 script called texi2pod.pl to convert the texinfo file to perl's pod
 documentation format, and then uses perl's pod2man program to convert it
 to *roff format, which is what manpages are and what the `man` program
 reads.

 openldap, on the other hand, doesn't install documentation in info format
 at all, only in *roff format. It distributes its documentation in *roff
 format in fact, but the *roff files it distributes are not the final files
 users will see in the `man` program; rather, they're templates that still
 need some processing. There are placeholders to be replaced with real
 values (like the openldap version number) which the build system does
 using `sed`, and include statements which need to be replaced with the
 contents of the files being included, which the build system does using
 `soelim`.
