libchemistry-elements-perl - 1.077-1 main

Chemistry::Elements provides an easy, object-oriented way to
keep track of your chemical data. Using either the atomic
number, chemical symbol, or element name you can construct
an Element object. Once you have an element object, you can
associate your data with the object by making up your own
methods, which the AUTOLOAD function handles. Since each
chemist is likely to want to use his or her own data, or
data for some unforesee-able property, this module does not
try to be a repository for chemical data.
