Libtextcat is a library with functions that implement the classification
technique described in Cavnar & Trenkle, "N-Gram-Based Text Categorization" [1].
It was primarily developed for language guessing, a task on which it is known to
perform with near-perfect accuracy.
The central idea of the Cavnar & Trenkle technique is to calculate a
"fingerprint" of a document with an unknown category, and compare this with the
fingerprints of a number of documents of which the categories are known. The
categories of the closest matches are output as the classification. A
fingerprint is a list of the most frequent n-grams occurring in a document,
ordered by frequency. Fingerprints are compared with a simple out-of-place
metric.

textproc/libtextcat: deprecate
Upstream disapeared, and LibreOffice adopted and adapted this program.
It has been renamed as libexttextcat, and can be replaced by the port
textproc/libexttextcat.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Don't quote {} in find -exec calls.
Braces are not shell metacharacters, and they do not need to be quoted.
By the time find parses its arguments and dicovers them, the quoting
will have been removed by the shell anyway.

Update CONFIGURE_ARGS for how we pass CONFIGURE_TARGET to configure script.
Specifically, newer autoconf (> 2.13) has different semantic of the
configure target. In short, one should use --build=CONFIGURE_TARGET
instead of CONFIGURE_TARGET directly. Otherwise, you will get a warning
and the old semantic may be removed in later autoconf releases.
To workaround this issue, many ports hack the CONFIGURE_TARGET variable
so that it contains the ``--build='' prefix.
To solve this issue, under the fact that some ports still have
configure script generated by the old autoconf, we use runtime detection
in the do-configure target so that the proper argument can be used.
Changes to Mk/*:
- Add runtime detection magic in bsd.port.mk
(Only the first 15 lines of the commit message are shown above )
Import patches (imported from OpenOffice.org 2.3 by Fedora, at least in
part). These patches, released under a BSD license, seem to improve the
accuracy of language detection, especially those that don't have a
Latin script.
