While there are tools called "localedef" in Solaris and Linux, this
tool does not share heritage with any other implementation.  It was
written independently by Garrett D'Amore while employed at Nexenta
Systems, and thus carries the Nexenta Copyright.

It was initially released under the CDDL license, but on 4 July 2014,
Nexenta reissued the source under the BSD 2-clause license.  This
code is part of the Illumos project.

Add localedef(1), a locale definition generator tool The localedef tool can read entire (and unmodified) CLDR posix definition files, and generate all 6 LC categories: LC_COLLATE, LC_CTYPE, LC_TIME, LC_NUMERIC, LC_MONETARY and LC_MESSAGES. This tool has a long history with Solaris. The Nexenta developers modified it to read CLDR files and created the much richer collation formats. The libc collation functions have to be modified to read the new format (called "BSD-1.0") and to handle the new data structures. The result will be that locale-sensitive tools and functions will now properly sort multibyte and unicode strings.
