 .SH DESCRIPTION
 .PP
-This series of C functions provides an interface whereby commands that
-are implemented in C can be evaluated, and invoke Tcl commands scripts
-and scripts, without consuming space on the C stack. The non-recursive
-evaluation is done by installing a \fItrampoline\fR, a small piece of
-code that invokes a command or script, and then executes a series of
-callbacks when the command or script returns.
+These functions provide an interface to the function stack that an interpreter
+iterates through to evaluate commands.  The routine behind a command is
+implemented by an initial function and any additional functions that the
+routine pushes onto the stack as it progresses.  The interpreter itself pushes
+functions onto the stack to react to the end of a routine and to exercise other

-The \fBTcl_NRCreateCommand\fR function creates a Tcl command in the
-interpreter designated by \fIinterp\fR that is prepared to handle
-nonrecursive evaluation with a trampoline. The \fIcmdName\fR argument
-gives the name of the new command. If \fIcmdName\fR contains any
-namespace qualifiers, then the new command is added to the specified
-namespace; otherwise, it is added to the global namespace. \fIproc\fR
-gives the procedure that will be called when the interpreter wishes to
-evaluate the command in an unoptimized manner, and \fInreProc\fR is
-the procedure that will be called when the interpreter wishes to

+\fBTcl_NRCreateCommand\fR, an alternative to \fBTcl_CreateObjCommand\fR,

 .PP
-When a command that is written to cope with evaluation via trampoline

-\fBTcl_NRCallObjProc\fR, the \fIinterp\fR, \fIclientData\fR,
-\fIobjc\fR and \fIobjv\fR parameters should be the same ones that were
-passed to \fIproc\fR. The \fInreProc\fR parameter should designate the

+\fBTcl_NREvalObjv\fR pushes a function that is like \fBTcl_EvalObjv\fR but

 .PP
-\fBTcl_NREvalObj\fR arranges for the script contained in \fIobjPtr\fR
-to be evaluated in the interpreter designated by \fIinterp\fR after
-the current command (which must be trampoline-enabled) returns. It is
-the method by which a command may invoke a script without consuming
-space on the C stack. Similarly, \fBTcl_NREvalObjv\fR arranges to
-invoke a single Tcl command whose words have already been separated
-and substituted. The \fIobjc\fR and \fIobjv\fR parameters give the
-words of the command to be evaluated when execution reaches the
-trampoline.
+\fBTcl_NRCmdSwap\fR is like \fBTcl_NREvalObjv\fR, but uses \fIcmd\fR, a token
+previously returned by \fBTcl_CreateObjCommand\fR or
+\fBTcl_GetCommandFromObj\fR, instead of resolving the first word of \fIobjv\fR.
+.  The name of this command must be the same as \fIobjv[0]\fR.

-\fBTcl_NRCmdSwap\fR allows for trampoline evaluation of a command whose

-\fBTcl_Command\fR token (returned from \fBTcl_CreateObjCommand\fR or

-the trampoline; this command must match the word in \fIobjv[0]\fR.
-The remaining arguments are as for \fBTcl_NREvalObjv\fR.
+\fBTcl_NRExprObj\fR pushes a function that evaluates \fIobjPtr\fR as an
+expression in the same manner as \fBTcl_ExprObj\fR but without consuming space
+on the C stack.
 .PP

-\fBTcl_NRExprObj\fR arranges for the expression contained in \fIobjPtr\fR
-to be evaluated in the interpreter designated by \fIinterp\fR after

-the method by which a command may evaluate a Tcl expression without consuming
-space on the C stack.  The argument \fIresultPtr\fR is a pointer to an
-unshared Tcl_Obj where the result of expression evaluation is to be written.
