update xkeyval and extract packages

Date: January 3, 2005 2:25:43 PM CET

On Sat, 1 Jan 2005, Hendri Adriaens uploaded updates to his packages xkeyval and extract ------------------------------------------------------------ xkeyval is an extension of the the keyval package and offers additional macros for setting keys and declaring and setting class or package options. The package allows the programmer to specify a prefix to the name of the macros it defines for keys, and to define families of key definitions; these all help use in documents where several packages define their own sets of keys. Location on CTAN: macros/latex/contrib/xkeyval License: lppl Changes: 1) Simplified some code for speed. 2) Updated the license info. 3) restructured package, changed a name of an internal file 4) pointer replacement macros have been updated in order to avoid capacity problems when pointers are nested deeply.

The package extract provides the means to extract specific content from a source document and write that to a target document. One could, for instance, use this to extract all exercises from lecture notes and generate an exercises book on the fly. Location on CTAN: macros/latex/contrib/extract License: lppl Changes: 1) Added conditional extraction with labels 2) Revised documentation 3) Added examples. 4) Updated the license info.

Thanks for the updates. For the CTAN Team Rainer Schöpf

extract – Extract parts of a document and write to another document

The package provides the means to extract specific content from a source document and write that to a target document. One could, for instance, use this to extract all exercises from lecture notes and generate an exercises book on the fly.

The package also provides an environment which writes its body entirely to the target file. Another environment will write to the target file, but will also execute the body. This allows to share code (for instance, a preamble) between the source document and the target file.

Finally, the package provides an interface to conditionally extract content. With a single package option, one can specify exactly which commands (counted from the start of the document) should be extracted and which not. This might be useful for extracting specific slides from a presentation and use them in a new file.
