Quoting https://tcl.tk/doc/tea:
"The Tcl Extension Architecture, or TEA, by John Ousterhout and others, is a
set of guidelines and techniques for the distribution, configuration,
compilation, and installation of Tcl extensions. TEA also provides a set of
utilities that operate accordingly. Many Tcl extensions leverage the TEA
utilities, which are designed to be easily customizable."
To facilitate the porting of TEA-based extensions, I have added the new "tea"
argument to USES=tcl. This argument prepares the autoconf environment by
setting GNU_CONFIGURE and sets some commonly used CONFIGURE_ARGS. Also, it
tries to figure out the correct extension name, sets TCL_PKG accordingly, and
adds it to PLIST_SUB.
I have modified a few ports to take advantage of this. More will come.
