manpath –
determine path

MANPATH is set,
manpath will simply display its contents
and issue a warning.

manpath will determine a suitable path
and display the results.

The path is determined using information gained
from the configuration and the user’s environment.
Do not issue warnings.

Produce a manpath consisting of all paths

man must override
the SYSTEM environment.

MANPATH displays its value
rather than determining it on the fly.

the value is determined from the content

comes at the end.
