 .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
+forms of control such as switching between in-progress stacks and the
+evaluation of other scripts at additional levels without adding frames to the C
+stack.  To execute a routine, the initial function for the routine is called
+and then a small bit of code called a \fItrampoline\fR iteratively takes
+functions off the stack and calls them, using the value of the last call as the
+value of the routine.
 .PP
-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
-evaluate the command using a trampoline. \fIdeleteProc\fR is a
-function that will be called before the command is deleted from the
-interpreter. When any of the three functions is invoked, it is passed
-the \fIclientData\fR parameter.
+\fBTcl_NRCallObjProc\fR calls \fInreProc\fR using a new trampoline.
 .PP
-\fBTcl_NRCreateCommand\fR deletes any existing command
-\fIname\fR already associated with the interpreter
-(however see below for an exception where the existing command
-is not deleted).
-It returns a token that may be used to refer
-to the command in subsequent calls to \fBTcl_GetCommandName\fR.
-If \fBTcl_NRCreateCommand\fR is called for an interpreter that is in
-the process of being deleted, then it does not create a new command,
-does not delete any existing command of the same name, and returns NULL.
+\fBTcl_NRCreateCommand\fR, an alternative to \fBTcl_CreateObjCommand\fR,
+resolves \fIcmdName\fR, which may contain namespace qualifiers, relative to the
+current namespace, creates a command by that name, and returns a token for the
+command which may be used in subsequent calls to \fBTcl_GetCommandName\fR.
+Except for a few cases noted below any existing command by the same name is
+first deleted.  If \fIinterp\fR is in the process of being deleted
+\fBTcl_NRCreateCommand\fR does not create any command, does not delete any
+command, and returns NULL.
 .PP
-The \fIproc\fR and \fInreProc\fR function are expected to conform to
-all the rules set forth for the \fIproc\fR argument to
-\fBTcl_CreateObjCommand\fR(3) (\fIq.v.\fR).
+\fBTcl_NREvalObj\fR pushes a function that is like \fBTcl_EvalObjEx\fR but
+consumes no space on the C stack.
 .PP
-When a command that is written to cope with evaluation via trampoline
-is invoked without a trampoline on the stack, it will usually respond
-to the invocation by creating a trampoline and calling the
-trampoline-enabled implementation of the same command. This call is done by
-means of \fBTcl_NRCallObjProc\fR. In the call to
-\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
-trampoline-enabled implementation of the command.
+\fBTcl_NREvalObjv\fR pushes a function that is like \fBTcl_EvalObjv\fR but
+consumes no space on the C stack.
 .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.
 .PP
-\fBTcl_NRCmdSwap\fR allows for trampoline evaluation of a command whose
-resolution is already known.  The \fIcmd\fR parameter gives a
-\fBTcl_Command\fR token (returned from \fBTcl_CreateObjCommand\fR or
-\fBTcl_GetCommandFromObj\fR) identifying the command to be invoked in
-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_NREvalObj\fR, \fBTcl_NREvalObjv\fR and \fBTcl_NRCmdSwap\fR
-all accept a \fIflags\fR parameter, which is an OR-ed-together set of
-bits to control evaluation. At the present time, the only supported flag
-available to callers is \fBTCL_EVAL_GLOBAL\fR.
-.\" TODO: Again, this is a lie. Do we want to explain TCL_EVAL_INVOKE
-.\"       and TCL_EVAL_NOERR?
-If the \fBTCL_EVAL_GLOBAL\fR flag is set, the script or command is
-evaluated in the global namespace. If it is not set, it is evaluated
-in the current namespace.
+All of the functions return \fBTCL_OK\fR if the evaluation of the script,
+command, or expression has been scheduled successfully.  Otherwise (for example
+if the command name cannot be resolved), they return \fBTCL_ERROR\fR and store
+a message as the interpreter's result.
 .PP
-\fBTcl_NRExprObj\fR arranges for the expression 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 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.
-If expression evaluation returns any code other than TCL_OK, the
-\fIresultPtr\fR value is left untouched.
-.PP
-All of the routines return \fBTCL_OK\fR if command or expression invocation
-has been scheduled successfully. If for any reason the scheduling cannot
-be completed (for example, if the interpreter is unable to find
-the requested command), they return \fBTCL_ERROR\fR with an
-appropriate message left in the interpreter's result.
-.PP
-\fBTcl_NRAddCallback\fR arranges to have a C function called when the
-current trampoline-enabled command in the Tcl interpreter designated
-by \fIinterp\fR returns.  The \fIpostProcPtr\fR argument is a pointer
-to the callback function, which must have arguments and return value

+ *	are possible.  The value objPtr might be parsed as an absolute
+ *	index value in the C signed int range.  Note that this includes
+ *	index values that are integers as presented and it includes index
+ *      arithmetic expressions. The absolute index values that can be
+ *	directly meaningful as an index into either a list or a string are
+ *	those integer values >= TCL_INDEX_START (0)
+ *	and < TCL_INDEX_AFTER (INT_MAX).
+ *      The largest string supported in Tcl 8 has bytelength INT_MAX.
+ *      This means the largest supported character length is also INT_MAX,
+ *      and the index of the last character in a string of length INT_MAX
+ *      is INT_MAX-1.
+ *
+ *      Any absolute index value parsed outside that range is encoded
+ *      using the before and after values passed in by the
+ *      caller as the encoding to use for indices that are either
+ *      less than or greater than the usable index range. TCL_INDEX_AFTER
+ *      is available as a good choice for most callers to use for
+ *      after. Likewise, the value TCL_INDEX_BEFORE is good for
+ *      most callers to use for before.  Other values are possible
+ *      when the caller knows it is helpful in producing its own behavior
+ *      for indices before and after the indexed item.
+ *
+ *      A token can also be parsed as an end-relative index expression.
+ *      All end-relative expressions that indicate an index larger
+ *      than end (end+2, end--5) point beyond the end of the indexed
+ *      collection, and can be encoded as after.  The end-relative
+ *      expressions that indicate an index less than or equal to end
+ *      are encoded relative to the value TCL_INDEX_END (-2).  The
+ *      index "end" is encoded as -2, down to the index "end-0x7ffffffe"
+ *      which is encoded as INT_MIN. Since the largest index into a
+ *      string possible in Tcl 8 is 0x7ffffffe, the interpretation of
+ *      "end-0x7ffffffe" for that largest string would be 0.  Thus,
+ *      if the tokens "end-0x7fffffff" or "end+-0x80000000" are parsed,
+ *      they can be encoded with the before value.
+ *
+ *      These details will require re-examination whenever string and
+ *      list length limits are increased, but that will likely also
+ *      mean a revised routine capable of returning Tcl_WideInt values.
+ *
+ * Returns:

 The project can be build by using `make`. Along with the usual `make`, `make clean` and `make install`, there are several other build targets, see the makefile for details. There are also makefiles for certain specific platforms.
 
+## Testing
+
 Tests are located in `demo/` and can be built in two flavors.
 * `make test` creates a test binary that is intended to be run against `mtest`. `mtest` can be built with `make mtest` and test execution is done like `./mtest/mtest | ./test`. `mtest` is creating test vectors using an alternative MPI library and `test` is consuming these vectors to verify correct behavior of ltm
 * `make test_standalone` creates a stand-alone test binary that executes several test routines.
