DESCRIPTION
Tcl_PutEnv sets an environment variable. The information is passed in a
single string of the form “NAME=value”. This procedure is intended to
be a stand-in for the UNIX putenv system call. All Tcl-based applica-
tions using putenv should redefine it to Tcl_PutEnv so that they will
interface properly to the Tcl runtime.
