Z:gnu-man-db-manpages--95f29d-If $B=3CMANPATH=3E is set, B=3C=25manp/en

If $B is set, B<%manpath%> displays its value rather than determining it on the fly. If $B is prefixed by a colon, then the value of the variable is appended to the list determined from the content of the configuration files. If the colon comes at the end of the value in the variable, then the determined list is appended to the content of the variable. If the value of the variable contains a double colon (B<::>), then the determined list is inserted in the middle of the value, between the two colons.
