+<P>collperf is a test program for comparing collation performance and key lengths of ICU, Windows native collation
+and Unix/POSIX collation. It operates on a file of lines (names, for example), and performs one of three tests:</P>
+
+<OL>
+ <LI>Sort Key generation. Report on key lengths and key generation times.
+ <LI>Binary search. Report the average time required to look up each of the names (file lines) from the file in
+ a sorted list of all of the names.
+ <LI>Quick Sort. Report the time required to sort the file in memory, using the C library qsort function. The file
+ order is randomized prior to the sort.
+</OL>

+-help Display this message.
+-file file_name utf-16 format file of names
+-locale name ICU locale to use. Default is en_US
+-langid 0x1234 Windows Language ID number. Default 0x409 (en_US)
+ see http://msdn.microsoft.com/library/psdk/winbase/nls_8xo3.htm
+-win Run test using Windows native services. (ICU is default)
+-unix Run test using Unix strxfrm, strcoll services.
+-uselen Use API with string lengths. Default is null-terminated strings
+-usekeys Run tests using sortkeys rather than strcoll
+-loop nnnn Loopcount for test. Adjust for reasonable total running time.
