Archives are files which contain a collection of other files plus information about them, such as their file name, owner, timestamps, and access permissions. The archive can be another file on the disk, a magnetic tape, or a pipe. GNU cpio supports the following archive formats: binary, old ASCII, new ASCII, crc, HPUX binary, HPUX old ASCII, old tar and POSIX.1 tar. By default, cpio creates binary format archives, so that they are compatible with older cpio programs. When it is extracting files from archives, cpio automatically recognizes which kind of archive it is reading and can read archives created on machines with a different byte-order.

Install cpio if you need a program to manage file archives.

Cpp is the GNU C-Compatible Compiler Preprocessor. Cpp is a macro processor which is used automatically by the C compiler to transform your program before actual compilation. It is called a macro processor because it allows you to define macros, abbreviations for longer constructs.

The C preprocessor provides four separate functionalities: the inclusion of header files (files of declarations that can be substituted into your program); macro expansion (you can define macros, and the C preprocessor will replace the macros with their definitions throughout the program); conditional compilation (using special preprocessing directives, you can include or exclude parts of the program according to various conditions); and line control (if you use a program to combine or rearrange source files into an intermediate file which is then compiled, you can use line control to inform the compiler about where each source line originated).

You should install this package if you are a C programmer and you use macros.

CrackLib tests passwords to determine whether they match certain security-oriented characteristics, with the purpose of stopping users from choosing passwords that are easy to guess. CrackLib performs several tests on passwords: it tries to generate words from a username and gecos entry and checks those words against the password; it checks for simplistic patterns in passwords; and it checks for the password in a dictionary.

CrackLib is actually a library containing a particular C function which is used to check the password, as well as other C functions. CrackLib is not a replacement for a passwd program; it must be used in conjunction with an existing passwd program.

CVS (Concurrent Version System) is a version control system that can record the history of your files (usually, but not always, source code). CVS only stores the differences between versions, instead of every version of every file you have ever created. CVS also keeps a log of who, when, and why changes occurred.

CVS is very helpful for managing releases and controlling the concurrent editing of source files among multiple authors. Instead of providing version control for a collection of files in a single directory, CVS provides version control for a hierarchical collection of directories consisting of revision controlled files. These directories and files can then be combined together to form a software release.

The mkbootdisk program creates a standalone boot floppy disk for booting the running system. The created boot disk will look for the root filesystem on the device mentioned in /etc/fstab and includes an initial ramdisk image which will load any necessary SCSI modules for the system.

Mkinitrd creates filesystem images for use as initial ramdisk (initrd) images. These ramdisk images are often used to preload the block device modules (SCSI or RAID) needed to access the root filesystem.

In other words, generic kernels can be built without drivers for any SCSI adapters which load the SCSI driver as a module. Since the kernel needs to read those modules, but in this case it isn't able to address the SCSI adapter, an initial ramdisk is used. The initial ramdisk is loaded by the operating system loader (normally LILO) and is available to the kernel as soon as the ramdisk is loaded. The ramdisk image loads the proper SCSI adapter and allows the kernel to mount the root filesystem. The mkinitrd program creates such a ramdisk using information found in the /etc/conf.modules file.

The mkisofs program is used as a pre-mastering program; i.e., it generates the ISO9660 filesystem. Mkisofs takes a snapshot of a given directory tree and generates a binary image of the tree which will correspond to an ISO9660 filesystem when written to a block device. Mkisofs is used for writing CD-ROMs, and includes support for creating bootable El Torito CD-ROMs.

Install the mkisofs package if you need a program for writing CD-ROMs.

This package provides source-level filters for Perl modules. Source filters alter the program text of a module before Perl sees it, much as a C preprocessor alters the source text of a C program before the compiler sees it.

Source filtering is an immensely powerful feature of recent versions of Perl. It allows one to extend the language itself (e.g. the Switch module), to simplify the language (e.g. Language::Pythonesque), or to completely recast the language (e.g. Lingua::Romana::Perligata). Effectively, it allows one to use the full power of Perl as its own, recursively applied, macro language.

The excellent Filter::Util::Call module (by Paul Marquess) provides a usable Perl interface to source filtering, but it is often too powerful and not nearly as simple as it could be.

Perl objects are blessed back to their original packaging; if the modules are installed on the system where the perl objects are reconstituted from xml, they will behave as expected. Intuitively, if the perl objects are converted and reconstituted in the same environment, all should be well.

This module, which is built as a subclass of XML::Parser, provides a parser for encoding map files, which are XML files. The file maps/encmap.dtd in the distribution describes the structure of these files.

XML::Grove is a tree-based object model for accessing the information set of parsed or stored XML, HTML, or SGML instances. XML::Grove objects are Perl hashes and arrays where you access the properties of the objects using normal Perl syntax.

This module provides ways to parse XML documents. It is built on top of XML::Parser::Expat, which is a lower level interface to James Clark's expat library. Each call to one of the parsing methods creates a new instance of XML::Parser::Expat which is then used to parse the document. Expat options may be provided when the XML::Parser object is created. These options are then passed on to the Expat object on each parse call. They can also be given as extra arguments to the parse methods, in which case they override options given at XML::Parser creation time.

This module provides a way to process XML documents. It is build on top of XML::Parser. XML::Twig offers a tree interface to the document, while allowing you to output the parts of it that have been completely processed. It allows minimal resource (CPU and memory) usage by building the tree only for the parts of the documents that need actual processing, through the use of the twig_roots and twig_print_outside_roots options.

This is the freedesktop.org shared MIME info database.

Many programs and desktops use the MIME system to represent the types of files. Frequently, it is necessary to work out the correct MIME type for a file. This is generally done by examining the file's name or contents, and looking up the correct MIME type in a database.

For interoperability, it is useful for different programs to use the same database so that different programs agree on the type of a file, and new rules for determining the type apply to all programs.

This specification attempts to unify the type-guessing systems currently in use by GNOME, KDE and ROX. Only the name-to-type and contents-to-type mappings are covered by this spec; other MIME type information, such as the default handler for a particular type, or the icon to use to display it in a file manager, are not covered since these are a matter of style.

In addition, freedesktop.org provides a shared database in this format to avoid inconsistencies between desktops. This database has been created by converting the existing KDE and GNOME databases to the new format and merging them together.

This package provides debug information for package shared-mime-info. Debug information is useful when developing applications that use this package or when debugging this package.
