The calc command may be used to do simple integer calculations or to convert numbers from one radix to another. Calc reads commands from stdin and prints the result to stdout. The inpout radix for mumbers may be decimal (default), octal (if starting with a '0') or hexadecimal (if starting with "0x"). The output is always printed in four radices: decimal, octal, hexadecimal, and binary. The decimal variant is printed in both signed and unsigned representation. The result is printed in two variants using 32 bit and 64 bit repesentations for the numbers.
compare is similar to cmp but faster and with better readable output. compare examines one file and standard in, or two files on a byte by byte basis, and prints the file position of the first difference it finds, first in decimal and then in hexadecimal, followed by the differing byte content in hexadecimal and a quoted character.
Makefiles is a high-level build system and suite of portability tools. It is meant to be easier to use than autoconf and generally superior. The package contains a set of rules that allows you to compile structured projects with small and uniformly structured makefiles. All rules are located in a central directory. Compiling the projects on different platforms can be done simultaneously without having to modify any of the makefiles that are located in the projects directories.
p is a pager like more or less. It is more conservative with screen handling and thus does not screw up the screen as easily as more or less. p uses its own termcap package with TERMPATH support that makes it easy to have a local .termcap file in the user's home directory to override bad termcap entries. p supports three text attributes for nroff: bold, italic, and bold-italic. p is able to find patterns in higlighted text, unlike more or less. p also filters out unprintable characters.
sdd is a replacement for a program called 'dd'. sdd is much faster than dd in cases where input block size (ibs) is not equal to the output block size (obs). Statistics are more easily understood than those from 'dd'. Timing available, -time option will print transfer speed Timing & Statistics available at any time with SIGQUIT (^\) Can seek on input and output Fast null input Fast null output. Support for the RMT (Remote Tape Server) protocol makes remote I/O fast and easy.
CFL (Compressed File Library) is meant for the save-files used by games, and other sorts of data files. Its features include pluggable class factories, easy CFL file creation at runtime, and the ability to have multiple separate CFL objects in memory at the same time. The package also includes a CFL testing tool to make it easier to port the library and to create additional plug-in compressors, preprocessors, and ciphers. It also includes a makecfl utility, which makes it easy to create ini files.
smake is a highly portable 'make' program that makes commands up to date based on rules in Makefiles and on the timestamps of the related files. It implements a complete superset of the features of the classical POSIX/Unix make program. It warns about typical misuse of dynamic macros that prevent portability of makefiles. Its automake features allow you to run scripts to automatically create rules for unknown platforms.
