+The base NPTL code for uClibc is from the glibc project located at
+<http://sourceware.org/glibc/>. The starting version was the HEAD of
+the glibc CVS repository dated 2005-05-06. Important changes from
+glibc will continue to be brought in as necessary until the version
+for uClibc is standing on its own. All of the files were originally
+brought over verbatim with no modifications. Obviously, these will
+undergo any necessary changes needed for integration into uClibc.
+Additionally (or subtractingly), the files and directories below
+were removed and not imported.
