18.14 Minor bug in ResignOrDraw() code caused Crafty to not offer draws
although it would accept them when appropriate. Rook vs Minor
is now evaluated as "neither side can win" an oversight in the
EvaluateWinner() code. minor bug in ResignOrDraw() would fail to
offer draws due to the +0.01/-0.01 draw scores returned by the
EGTB probe code.
18.15 change in endgame draw recognition to handle the case where one
side appears to be in a lost ending but is stalemated. the code
now evaluates such positions as "DrawScore()" instead. the code
to accept/decline draws has been modified. when a draw offer is
received, a global variable "draw_offer_pending" is set to 1.
when the search for a move for crafty terminates, crafty then
uses this value to decide whether to accept or decline the draw.
this means that the accept/decline won't happen until _after_ the
search has a chance to see if something good is happening that
should cause the draw to be declined, closing a timing hole that
used to exist that let a few "suspects" get away with draws that
should not have happened (ie crafty has - scores for a long time,
the opponent suddenly fails low and sees he is losing and offers
a draw quickly. Crafty would accept before doing a search and
noticing that it was suddenly winning.) minor evaluation change
to notice that K+B+right RP vs K+B is not necessarily won if the
weaker side has a bishop of the right color.

$NetBSD: README,v 1.13 2001/12/03 21:33:56 agc Exp $ Welcome to the NetBSD Packages Collection ========================================= In brief, the NetBSD Packages Collection is a set of software utilities and libraries which have been ported to NetBSD. The packages collection software can retrieve the software from its home site, assuming you are connected in some way to the Internet, verify its integrity, apply any patches, configure the software for NetBSD, and build it. Any prerequisite software will also be built and installed for you. Installation and de-installation of software is managed by the packaging utilities. The packages collection is made into a tar_file every week: ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-current/tar_files/pkgsrc.tar.gz and you can sup the pkgsrc tree using the `pkgsrc' name for the collection. The pkgsrc tree is laid out in various categories, and, within that, the various packages themselves. You need to have root privileges to install packages. We are looking at ways to remove this restriction. + To install a package on your system, you need to change into the directory of the package, and type "make install". + If you've made a mistake, and decided that you don't want that package on your system, then type "pkg_delete <pkg-name>", or "make deinstall" while in the directory for the package. + To find out all the packages that you have installed on your system, type "pkg_info". + To remove the work directory, type "make clean", and "make clean-depends" will clean up any working directories for other packages that are built in the process of making your package. + Optionally, you can periodically run "make clean" from the top level pkgsrc directory. This will delete extracted and built files, but will not affect the retreived source sets in pkgsrc/distfiles. + You can set variables to customise the behaviour (where packages are installed, various options for individual packages etc), by setting variables in /etc/mk.conf. The pkgsrc/mk/bsd.pkg.defaults.mk gives the defaults which are used in pkgsrc. This file can be used as a guide to set values in /etc/mk.conf - it is only necessary to set values where they differ from the defaults. The best way to find out what packages are in the collection is to move to the top-level pkgsrc directory (this will usually be /usr/pkgsrc), and type "make readme". This will create a file called README.html in the top-level pkgsrc directory, and also in all category and package directories. You can then see what packages are available, along with a short (one-line) comment about the function of the package, and a pointer to a fuller description, by using a browser like lynx (see pkgsrc/www/lynx) or Mozilla (pkgsrc/www/mozilla), or Communicator. This is also available online as ftp://ftp.netbsd.org/pub/NetBSD/packages/pkgsrc/README.html. Another way to find out what packages are in the collection is to move to the top-level pkgsrc directory and type "make index". This will create pkgsrc/INDEX which can be viewed via "make print-index | more". You can also search for particular packages or keywords via "make search key=<somekeyword>". It is also possible to use the packaging software to install pre-compiled binary packages by typing "pkg_add <URL-of-binary-pkg>". To see what binary packages are available, see: ftp://ftp.netbsd.org/pub/NetBSD/packages/<release>/<arch>/All/ where <release> is the NetBSD release, and <arch> is the hardware architecture. One limitation of using binary packages provided from ftp.netbsd.org is that all mk.conf options were set to the defaults at compile time. LOCALBASE, in particular, defaults to /usr/pkg, so non-X binaries will be installed in /usr/pkg/bin, man pages will be installed in /usr/pkg/man... When a packaged tool has major compile time choices, such as support for multiple graphic toolkit libraries, the different options may be available as separate packages. For more information on the packages collection see the file Packages.txt file in the same place where you found this README, usually in the top-level pkgsrc dir. directory.
