"The Adobe LiveCycle Reader Extensions is software that users can use
to enable some features, in Acrobat Reader (now Adobe Reader) 5.1 and
later on a per file basis. These are features otherwise found in the
full licensed product Adobe Acrobat.

For example, Adobe Reader cannot normally save filled in forms or
apply digital signatures. If LiveCycle Reader Extensions is purchased
with suitable options, it can prepare files that Reader can save or
sign."
