There shouldn't be a problem with releasing it by just ripping it
straight out of the Tcl sources, as it is not tightly bound to the
rest of Tcl.  Indeed, apart from a bit of code relating to dynamic
string management and some code relating to unicode-aware character
management, Henry's RE code is completely separate from Tcl (well, it
is in Tcl8.3.0 which is the last version I've got a handy source tree
to grep through for at the moment... :^)
