Many of Linux-Mandrake's users who don't need to buy the boxed
product have requested to give money directly to support the
development of all parts of the distribution.
The rule is that you have to choose a project that you want to
support, and then you choose the amount you want to give. The money
will then be directed to the project you choose. The more you
donate, the more people can be hired to improve Linux-Mandrake and
other free-software projects! :-)
