LibRaw is a library for reading RAW files obtained from digital photo cameras (CRW/CR2, NEF, RAF, DNG, and others).

Hugin is an easy to use panoramic imaging toolchain with a graphical user interface. It can be used to assemble a mosaic of photographs into a complete panorama and stitch any series of overlapping pictures.

Ansel is an photo-editing software for digital artists, designed to help you achieve your own interpretation of raw digital photographs.

Enblend blends away the seams in a panoramic image mosaic using a multi-resolution spline. Enfuse merges different exposures of the same scene to produce an image that looks much like a tone-mapped image.

This package contains the class loader class used by Composer to build its autoloading feature. This package is used by the composer-build-system to build its own store-aware autoloading feature.

PHP (PHP Hypertext Processor) is a server-side (CGI) scripting language designed primarily for web development but is also used as a general-purpose programming language. PHP code may be embedded into HTML code, or it can be used in combination with various web template systems, web content management systems and web frameworks.

Npiet is an interpreter for the Piet programming language. Instead of text, Piet programs are pictures. Commands are determined based on changes in color.

This package includes:

1. npiet, a Piet interpreter with debugging capabilities

2. npiet-foogol, a program that builds a Piet program from Foogol, an Algol-like language

3. npietedit, an editor for Piet programs.

This package provides a compiler and assembler that target the Piet graphical programming language.

piet-assembler converts Piet assembler instructions (e.g., push, add, switch, outn) and directives into an executable netpbm image of the corresponding Piet program.

piet-compiler compiles a C-like high-level language into assembly source understood by piet-assembler. It supports common arithmetic and boolean logic operators (though not bitwise manipulation), flow control (if, for, while), recursive functions, in-line assembler, and input/output intrinsics. The only supported data type is the integer.

The language is documented only by the compiler's Perl source code and the included samples.

pkgconf is a program which helps to configure compiler and linker flags for development libraries. It is similar to pkg-config from freedesktop.org. libpkgconf is a library which provides access to most of pkgconf's functionality, to allow other tooling such as compilers and IDEs to discover and use libraries configured by pkgconf.

pkg-config is a helper tool used when compiling applications and libraries. It helps you insert the correct compiler options on the command line so an application can use gcc -o test test.c `pkg-config --libs --cflags glib-2.0` for instance, rather than hard-coding values on where to find glib (or other libraries). It is language-agnostic, so it can be used for defining the location of documentation tools, for instance.

drawterm is a client for connecting venerable systems to Plan 9 systems. It behaves like a Plan 9 kernel and will attempt to reconstruct a Plan 9 terminal-like experience from a non-Plan 9 system.

Diod is a multi-threaded, user space file server that speaks 9P2000.L protocol.

Plan 9 from User Space (aka plan9port) is a port of many Plan 9 programs from their native Plan 9 environment to Unix-like operating systems.

YouPlot is a command line tool that draws plots on the terminal, powered by UnicodePlot gem. It provides commands youplot and uplot (shorthand) are provided, and supports chart types of barplot, histogram, lineplot, scatter, density, boxplot, and count.

Asymptote is a powerful descriptive vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. Asymptote provides for figures the same high-quality level of typesetting that LaTeX does for scientific text.

Guile-Charting is a Guile Scheme library to create bar charts and graphs using the Cairo drawing library.

UnicodePlot provides the feature to make charts with Unicode characters. Supported charts are: barplot, boxplot, densityplot, histogram, lineplot, and scatterplot.

Guile-Plotutils is a Guile binding to the venerable GNU Plotutils plotting and graphing library. If you want to make graphs that look like you went to university in the 1990s, this is the library for you.

Ploticus is a non-interactive software package for producing plots, charts, and graphics from data. Ploticus is good for automated or just-in-time graph generation, handles date and time data nicely, and has basic statistical capabilities. It allows significant user control over colors, styles, options and details.

GNU Plotutils is a package for plotting and working with 2D graphics. It includes the C library libplot and the C++ libplotter library for exporting 2D vector graphics in many file formats. It also has support for 2D vector graphics animations. The package also contains command-line programs for plotting scientific data.

PLplot is a software package for creating scientific plots which core library can be used to create standard x-y plots, semi-log plots, log-log plots, contour plots, 3D surface plots, mesh plots, bar charts and pie charts. Multiple graphs (of the same or different sizes) may be placed on a single page, and multiple pages are allowed for those device formats that support them.

PLplot has support for plot symbols and text specified by the user in the UTF-8 encoding of Unicode. This means for our many Unicode-aware devices that plot symbols and text are only limited by the collection of glyphs normally available via installed system fonts. Furthermore, a large subset of our Unicode-aware devices also support complex text layout (CTL) languages such as Arabic, Hebrew, and Indic and Indic-derived CTL scripts such as Devanagari, Thai, Lao, and Tibetan. Thus, for these PLplot devices essentially any language that is supported by Unicode and installed system fonts can be used to label plots.
