guide and portfile man page: document missing keywords

[mascguy (Christopher Nielsen)]

While our MacPorts Guide is quite extensive, there are a few portfile keywords missing. And while many have previously been identified in tickets, there are still a few that have not.

Per @jmroot, some items are documented via the man page for portfile. And for those that are, we can update the guide with that info. Such cases are:

• installs_libs
• add_users - issue:38440

Some others are missing from both:

• use_dmg - issue:56036
• configure.sdkroot, configure.macosx_deployment_target - issue:39083
• startupitem.user, startupitem.group - issue:13807

And finally, some are need additional work/clarification, before we can document:

• master_site_local, patch_site_local, archive_site_local - issue:62952, waiting on: issue:62143

There is documentation for installs_libs in the portfile man page.

Replying to jmroot:

There is documentation for installs_libs in the portfile man page.

Indeed there is, along with detail for add_users. That makes things easier, as we can reconcile from the man page, when possible.

Thanks for the heads-up Josh!

Added two more to the list of items not documented at all: startupitem.user and startupitem.group.

PR created, to document options startupitem.user/startupitem.group in the manpage for portfile:
