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
       applications  using  putenv  should redefine it to Tcl_PutEnv so that they will interface properly to the
       Tcl runtime.
