// // Tcl_CreateObjCommand defines a new command in interp and associates it with
// // procedure proc such that whenever name is invoked as a Tcl command (e.g.,
// // via a call to Tcl_EvalObjEx) the Tcl interpreter will call proc to process
// // the command.
// //
// // Tcl_CreateObjCommand deletes any existing command name 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 Tcl_GetCommandName. If name contains any ::
// // namespace qualifiers, then the command is added to the specified namespace;
// // otherwise the command is added to the global namespace. If
// // Tcl_CreateObjCommand is called for an interpreter that is in the process of
// // being deleted, then it does not create a new command and it returns NULL.
// // proc should have arguments and result that match the type Tcl_ObjCmdProc:
// //
// //	typedef int Tcl_ObjCmdProc(
// //	        ClientData clientData,
// //	        Tcl_Interp *interp,
// //	        int objc,
// //	        Tcl_Obj *const objv[]);
// //
// // When proc is invoked, the clientData and interp parameters will be copies of
// // the clientData and interp arguments given to Tcl_CreateObjCommand.
// // Typically, clientData points to an application-specific data structure that
// // describes what to do when the command procedure is invoked. Objc and objv
// // describe the arguments to the command, objc giving the number of argument
// // values (including the command name) and objv giving the values of the
// // arguments. The objv array will contain objc values, pointing to the argument
// // values. Unlike argv[argv] used in a string-based command procedure,
// // objv[objc] will not contain NULL.
// //
// // Additionally, when proc is invoked, it must not modify the contents of the
// // objv array by assigning new pointer values to any element of the array (for
// // example, objv[2] = NULL) because this will cause memory to be lost and the
// // runtime stack to be corrupted. The const in the declaration of objv will
// // cause ANSI-compliant compilers to report any such attempted assignment as an
// // error. However, it is acceptable to modify the internal representation of
// // any individual value argument. For instance, the user may call
// // Tcl_GetIntFromObj on objv[2] to obtain the integer representation of that
// // value; that call may change the type of the value that objv[2] points at,
// // but will not change where objv[2] points.
// //
// // proc must return an integer code that is either TCL_OK, TCL_ERROR,
// // TCL_RETURN, TCL_BREAK, or TCL_CONTINUE. See the Tcl overview man page for
// // details on what these codes mean. Most normal commands will only return
// // TCL_OK or TCL_ERROR. In addition, if proc needs to return a non-empty
// // result, it can call Tcl_SetObjResult to set the interpreter's result. In the
// // case of a TCL_OK return code this gives the result of the command, and in
// // the case of TCL_ERROR this gives an error message. Before invoking a command
// // procedure, Tcl_EvalObjEx sets interpreter's result to point to a value
// // representing an empty string, so simple commands can return an empty result
// // by doing nothing at all.
// //
// // The contents of the objv array belong to Tcl and are not guaranteed to
// // persist once proc returns: proc should not modify them. Call
// // Tcl_SetObjResult if you want to return something from the objv array.
// //
// // Ordinarily, Tcl_CreateObjCommand deletes any existing command name already
// // associated with the interpreter. However, if the existing command was
// // created by a previous call to Tcl_CreateCommand, Tcl_CreateObjCommand does
// // not delete the command but instead arranges for the Tcl interpreter to call
// // the Tcl_ObjCmdProc proc in the future. The old string-based Tcl_CmdProc
// // associated with the command is retained and its address can be obtained by
// // subsequent Tcl_GetCommandInfo calls. This is done for backwards
// // compatibility.
// //
// // DeleteProc will be invoked when (if) name is deleted. This can occur through
// // a call to Tcl_DeleteCommand, Tcl_DeleteCommandFromToken, or
// // Tcl_DeleteInterp, or by replacing name in another call to
// // Tcl_CreateObjCommand. DeleteProc is invoked before the command is deleted,
// // and gives the application an opportunity to release any structures
// // associated with the command. DeleteProc should have arguments and result
// // that match the type Tcl_CmdDeleteProc:
// //
// //	typedef void Tcl_CmdDeleteProc(
// //	        ClientData clientData);
// //
// // The clientData argument will be the same as the clientData argument passed
// // to Tcl_CreateObjCommand.

// // Tcl_SetVar2Ex, Tcl_SetVar, Tcl_SetVar2, and Tcl_ObjSetVar2 will create a new

// // to the value given by newValuePtr or newValue and return a pointer to the
// // variable's new value, which is stored in Tcl's variable structure.
// // Tcl_SetVar2Ex and Tcl_ObjSetVar2 take the new value as a Tcl_Obj and return
// // a pointer to a Tcl_Obj. Tcl_SetVar and Tcl_SetVar2 take the new value as a
// // string and return a string; they are usually less efficient than
// // Tcl_ObjSetVar2. Note that the return value may be different than the
// // newValuePtr or newValue argument, due to modifications made by write traces.
// // If an error occurs in setting the variable (e.g. an array variable is
// // referenced without giving an index into the array) NULL is returned and an
// // error message is left in interp's result if the TCL_LEAVE_ERR_MSG flag bit
// // is set.
// //
// // The name of a variable may be specified to these procedures in four ways:
// //
// // 1. If Tcl_SetVar, Tcl_GetVar, or Tcl_UnsetVar is invoked, the variable name
// // is given as a single string, varName. If varName contains an open
// // parenthesis and ends with a close parenthesis, then the value between the
// // parentheses is treated as an index (which can have any string value) and the
// // characters before the first open parenthesis are treated as the name of an
// // array variable. If varName does not have parentheses as described above,
// // then the entire string is treated as the name of a scalar variable.
// //
// // 2. If the name1 and name2 arguments are provided and name2 is non-NULL, then
// // an array element is specified and the array name and index have already been
// // separated by the caller: name1 contains the name and name2 contains the
// // index. An error is generated if name1 contains an open parenthesis and ends
// // with a close parenthesis (array element) and name2 is non-NULL.
// //
// // 3. If name2 is NULL, name1 is treated just like varName in case [1] above
// // (it can be either a scalar or an array element variable name).
// //
// // The flags argument may be used to specify any of several options to the
// // procedures. It consists of an OR-ed combination of the following bits.
// //
// //	TCL_GLOBAL_ONLY
// //
// // Under normal circumstances the procedures look up variables as follows. If a
// // procedure call is active in interp, the variable is looked up at the current
// // level of procedure call. Otherwise, the variable is looked up first in the
// // current namespace, then in the global namespace. However, if this bit is set
// // in flags then the variable is looked up only in the global namespace even if
// // there is a procedure call active. If both TCL_GLOBAL_ONLY and
// // TCL_NAMESPACE_ONLY are given, TCL_GLOBAL_ONLY is ignored.
// //
// //	TCL_NAMESPACE_ONLY
// //
// // If this bit is set in flags then the variable is looked up only in the
// // current namespace; if a procedure is active its variables are ignored, and
// // the global namespace is also ignored unless it is the current namespace.
// //
// //	TCL_LEAVE_ERR_MSG
// //
// // If an error is returned and this bit is set in flags, then an error message
// // will be left in the interpreter's result, where it can be retrieved with
// // Tcl_GetObjResult or Tcl_GetStringResult. If this flag bit is not set then no
// // error message is left and the interpreter's result will not be modified.
// //
// //	TCL_APPEND_VALUE
// // If this bit is set then newValuePtr or newValue is appended to the current
// // value instead of replacing it. If the variable is currently undefined, then
// // the bit is ignored. This bit is only used by the Tcl_Set* procedures.
// //
// //	TCL_LIST_ELEMENT
// //
// // If this bit is set, then newValue is converted to a valid Tcl list element
// // before setting (or appending to) the variable. A separator space is appended
// // before the new list element unless the list element is going to be the first
// // element in a list or sublist (i.e. the variable's current value is empty, or
// // contains the single character “{”, or ends in “ }”). When appending, the
// // original value of the variable must also be a valid list, so that the
// // operation is the appending of a new list element onto a list.
