This update changes the following:
- adds TCL83_MAN and TCLSH_WRAPPER to OPTIONS
- removes pseudo-installation of tclsh in favour of new lang/tcl-tk-wrapper port
- adds support for NO_INSTALL_MANPAGES knob
Portlint -A and tinderbox do not complain.
I would like to take maintainership of lang/tcl83 (there is no maintainer).
