+# $EPIC: tcl_function.txt,v 1.2 2007/02/20 03:54:29 jnelson Exp $
+======Synopsis:======
+$tcl(//tcl statement//)
+======Purpose:======
+If the client was linked with an embedded tcl interpreter, the //tcl statement//
+shall be executed by tcl.  If the client was not linked against tcl, then no
+action shall take place.
+As all //tcl statement//s resolve to a (tcl) value, that (tcl)
+value shall be converted into a string and returned.
+This means the return value shall not be "binary data" (have embedded nuls)
+If the //tcl statement// has an error, the result is undefined, but usually
+an error message is output to the window and the empty string is returned.
+Please remember that all function call arguments are subject to ircII
+expansion BEFORE the function call occurs.  You must ensure that any chars
+that are special to both ircII and ruby are quoted so ircII doesn't try
+to honor them.
+You can call back to the client from ruby.  See /[[tcl command|tcl]] for
+details.
+======Practical:======
+$tcl() is useful for loading tcl scripts and modules, defining
+simple tcl functions, retrieving variables from within tclspace and
+other general maintenance of the tcl environment.
+======Returns:======
+The Tcl_GetStringResult() result after calling Tcl_Eval() on //tcl statement//.
+======Examples:======
+Someone want to provide me examples?
+======History:======
+The TCL function first appeared in EPIC4-1.1.8.
