# USE_TCL		- Add library dependency on Tcl. If no version is given by the maintainer
#			  via the port or by the user via defined variable try to find the highest
#			  stable installed version.
#			  Available values: yes 86+ 85+ 84+ 85 84
#			  NOTE: - default value 86 is used in case of USE_TCL=yes
#
# USE_TCL_BUILD		- Add buildtime dependency on Tcl (tclsh).
#			  Available values: see USE_TCL
#			  NOTE: - has no effect if USE_TCL is defined
#
# USE_TCL_RUN		- Add runtime dependency on Tcl (tclsh).
#			  Available values: see USE_TCL
#			  NOTE: - has no effect if USE_TCL is defined
#				- value is implied by USE_TCL_BUILD (if defined)
#
# USE_TCL_WRAPPER	- Depend on the tclsh wrapper to run. Ports that do not explicitly require
#			  a specific tclsh version may use this.
#			  The tclsh wrapper script installs into ${LOCALBASE}/bin/tclsh
#			  NOTE: - USE_TCL_WRAPPER and USE_TCL can be used together
#			        - ports using the wrapper should support default Tcl (8.6)
##
# INVALID_TCL_VER	- This variable contains a list of Tcl versions not supported by the port.
#			  This setting is effective only when USE_TCL is set to a range (e.g. 85+)
# WITH_TCL_VER		- User defined global variable to set Tcl version
#			  This variable is effective only if USE_TCL is set to a range (e.g. 85+)
#			  and WITH_TCL_VER points inside that range.
#			  NOTE: INVALID_TCL_VER takes precedence
# <UNIQUENAME>_WITH_TCL_VER	- User defined port specific variable to set Tcl version
##
# TCL_VER		- Detected by bsd.tcl.mk. Contains the version number of Tcl to be used.
#
##
# USE_TK		- Add library dependency on Tk. If no version is given by the maintainer
#			  via the port or by the user via defined variable try to find the highest
#			  stable installed version.
#			  Avaliable values: yes 86+ 85+ 84+ 85 84
#			  NOTE: - overrides USE_TCL
#			        - default value 86 is used in case of USE_TK=yes
#
# USE_TK_BUILD		- Add buildtime dependency on Tk (wish).
#			  Available values: see USE_TK
#			  NOTE: - has no effect if USE_TK is defined
#
# USE_TK_RUN		- Add runtime dependency on Tk (wish).
#			  Available values: see USE_TK
#			  NOTE: - has no effect if USE_TK is defined
#				- value is implied by USE_TK_BUILD (if defined)
#
# USE_TK_WRAPPER	- Depend on the wish wrapper to run. Ports that do not explicitly require
#			  a specific wish version may use this.
#			  The wish wrapper script installs into ${LOCALBASE}/bin/wish
#			  NOTE: - USE_TK_WRAPPER and USE_TK can be used together.
#			        - ports using the wrapper should support default Tk (8.6)
##
# INVALID_TK_VER	- This variable contains a list of Tk versions not supported by the port
#			  This setting is effective only when USE_TK is set to a range (e.g. 85+)
# WITH_TK_VER		- User defined global variable to set Tk version.
#			  This variable is effective only if USE_TK is set to a range (e.g. 85+)
#			  and WITH_TK_VER points inside that range.
#			  NOTE: overrides WITH_TCL_VER.
# <UNIQUENAME>_WITH_TK_VER	- User defined port specific variable to set Tk version
#			  NOTE: overrides <UNIQUENAME>_WITH_TCL_VER.
##
# TCL_LIBDIR		- Path where tcl libraries can be found
#
# TCL_INCLUDEDIR	- Path where tcl C headers can be found
##
# TK_LIBDIR		- Path where tk libraries can be found
#
# TK_INCLUDEDIR 	- Path where tk C headers can be found
##
# TCLSH			- Path to tclsh executable respecting Tcl version
#			  or to the tclsh wrapper if USE_TCL_WRAPPER is set
#
# WISH			- Path to wish executable respecting Tk version
#			  or to the wish wrapper if USE_TK_WRAPPER is set
#
##
# PATCH_TCL_SCRIPTS	- List of tcl scripts that need to be patched to replace
# 			  tclsh calls with tclsh${TK_VER} calls. Also note that
# 			  post-patch target is used.
#
# PATCH_TK_SCRIPTS	- List of tcl scripts that need to be patched to replace
