This the Unix port of the Amiga XPK library.
The XPK system consists of a master library (libxpkmaster.so) and several
(un)packer sublibraries (libxpkXXXX.so). Application programs only use the
master library directly: the master library takes care of loading and using
the sublibraries. Each sublibrary implements one type of compression.
There are different libraries for different types of data. When unpacking the
applications do not need to know which library was used to pack the data --
the appropriate library needs to be installed.
Zip is a compression and file packaging utility. It is compatible with
PKZIP 2.04g (Phil Katz ZIP) for MSDOS systems. There is a companion to zip
called unzip (of course) which you can also install from the ports/package
system.
Sometimes, when you run 2 different .ZIP programs on the same data
(PKZIP & KZIP for example), some files get compressed better in one
program, while other files get compressed better in the other.
ZIPMIX will take the best files from each one and create a new
output file, which is guaranteed to be equal to or smaller in size
to both of the input files.
ZIPMIX can also be used to perform boolean operations on ZIP files,
such as merging 2 ZIP files together, or updating a new file (with
some tricks).
Zutils is a collection of utilities able to deal with any combination
of compressed and non-compressed files transparently. If any given
file, including standard input, is compressed, its decompressed
content is used. Compressed files are decompressed on the fly; no
temporary files are created.
The provided utilities are:
Zcat - Decompresses and copies files to standard output.
Zcmp - Decompresses and compares two files byte by byte.
Zdiff - Decompresses and compares two files line by line.
Zgrep - Decompresses and searches files for a regular expression.
Ztest - Tests integrity of compressed files.
Zupdate - Recompresses files to lzip format.
The supported compressors are bzip2, gzip, lzip, and xz.
This program converts OpenStreetMap data into a map that can be
loaded onto a Garmin GPS device. It does the conversion in one step
without depending on any other program.
Phoon displays the phase of the moon, either currently or at a
specified date / time. Unlike other such programs, which just
tell you how long since first quarter or something like that,
phoon shows you the phase with a cute little picture. You can
vary the size of the picture with the -l flag, but only some
sizes have pictures defined - other sizes use @'s.
ptiger is a Tcl/Tk/Tkgeomap script that uses wdgeomap to display U.S.
Census Burea populated places on an interactive geographic map.
To run it, type ptiger on the command line. After a few seconds, a map
should appear. Adjust the view by Dragging or Double-Clicking. As the
cursor moves, a label below the map displays the cursor location and
the azimuth and range from the + marker to the cursor. Move the + marker
by Right-Double-Clicking. The map has dots at places with population
greater than a user selected threshold. Moving the cursor over a dot
labels the place with its name and displays the population in another
label below the map. In addition to the wdgeomap menus, a Places menu
enables adjustment of the population threshold and dot size. There is
also a Find menu that does a case insensitive regular expression search
for a named place.
py-RO is a collection of utilities including general algorithms,
astronomical transformations and Tkinter widgets.
SAOimage (pronounced S-A-0-image) displays astronomical images in the X11
window environment. It was written by Mike Van Hilst while he was at the
Smithsonian Astrophysical Observatory (SAO) in 1990 and is now maintained by
Doug Mink also at the SAO.
Online help and documentation are on the webpage.
Image files can be read directly, or image data may be passed through a
named pipe (Unix) or a mailbox (VMS) from IRAF display tasks. SAOimage
provides a large selection of options for zooming, panning, scaling,
coloring, pixel readback, display blinking, and region specification. User
interactions are generally performed with the mouse, but keyboard
alternatives are often available.
The SAOimage desktop includes, a main image display window, a button menu
panel, a display magnifier, a pan and zoom reference image, and a color bar.
A color table graph window can be brought up by clicking on the color bar.
WeatherSpect provides a reasonably accurate simulation of what the weather looks
like outside, in ASCII art. It includes rain, snow, lightning, sleet, and hail.
The windspeed and cloudiness are reflected in the velocity and quantity of
clouds. There are trees that age, reproduce and die over the course of an hour,
and a sun and moon that follow the actual sun and moonrise. There's also a
dancing turtle.
