#### istarget Procedure ¶

Tests for a particular target environment. If the currently configured target matches the argument string, the result is 1 ; otherwise the result is 0. pattern must be a full three-part configure triplet; in particular, you may not use the shorter aliases supported by `configure` (but you can use Tcl globbing to specify a range of triplets). If called with no arguments or an empty pattern, this procedure returns the target triplet.
