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.
