##  For a central overview of all packages and a collection of all package
##  archives it is necessary to have two files accessible which should be
##  contained in each package:
##     - A README file, containing a short abstract about the package
##       content and installation instructions.
##     - The file you are currently reading or editing!
##  You must specify URLs for these two files, these allow to automate 
##  the updating of package information on the GAP Website, and inclusion
##  and updating of the package in the GAP distribution.
##

  PackageInfoURL := "http://cadigweb.ew.usna.edu/~wdj/gap/GUAVA/PackageInfo.g",

##  Here you  must provide a short abstract explaining the package content 
##  in HTML format (used on the package overview Web page) and an URL 
##  for a Webpage with more detailed information about the package
##  (not more than a few lines, less is ok):
##  Please, use '<span class="pkgname">GAP</span>' and
##  '<span class="pkgname">MyPKG</span>' for specifing package names.
##  

  AbstractHTML := 
    "<span class=\"pkgname\">GUAVA</span> is a <span class=\"pkgname\">GAP</span> package for computing with codes. <span class=\"pkgname\">GUAVA</span> can construct unrestricted (non-linear), linear and cyclic codes; transform one code into another (for example by puncturing); construct a new code from two other codes (using direct sums for example); perform decoding/error-correction; and can calculate important data of codes (such as the minumim distance or covering radius) quickly.

##  On the GAP Website there is an online version of all manuals in the
##  GAP distribution. To handle the documentation of a package it is
##  necessary to have:
##     - an archive containing the package documentation (in at least one 
##       of HTML or PDF-format, preferably both formats)
##     - the start file of the HTML documentation (if provided), *relative to
##       package root*
##     - the PDF-file (if provided) *relative to the package root*
##  For links to other package manuals or the GAP manuals one can assume 
##  relative paths as in a standard GAP installation. 
##  Also, provide the information which is currently given in your packages 
##  init.g file in the command DeclarePackage(Auto)Documentation
##  (for future simplification of the package loading mechanism).
##  
##  Please, don't include unnecessary files (.log, .aux, .dvi, .ps, ...) in
##  the provided documentation archive.
