"contrib" packages
ALL the "contrib" packages are INCLUDED with the distribution of CoCoA-4.6
(they are in the directory packages/contrib/) :
How to use "contrib" packages
When you download a new or updated package, save it in the CoCoA-4.6 directory packages/contrib/.
To know how to use a package, run CoCoA and type
$contrib/"package_name".Man().
This command gives the suggested alias for the package and the syntax,
description and examples of the main functions.
To know the version of a package, run CoCoA and type
$contrib/"package_name".About()
Starting from CoCoA-4.3:
all contributed
packages are in the directory packages/contrib/
the extension is ".cpkg" [instead of ".pkg"].
most aliases for packages are predefined: type
"Aliases()" to get the list.
Starting fron CoCoA-4.2 the contributors names are no longer part of the
name of their packages. (see examples below)
EXAMPLES:
- To know how to use intprog.cpkg, run CoCoA and type
$contrib/intprog.Man()
[or simply IP.Man()]
- To know the version of primary.cpkg, run CoCoA and type
$contrib/primary.About()
[or simply P.About()]
- The old syntax
$contrib/biro/primary.About()
no longer works!
Bug reports, questions, and suggestions should be sent to the authors.
