Adobe Acrobat is a family of computer programs developed by Adobe Systems,
designed to view, create, manipulate
and manage files in Adobe's Portable Document Format (PDF).
Some software in the family is commercial, and some is freeware.
Adobe Reader (formerly Acrobat Reader) is available as a no-charge
download from Adobe's web site, and allows the viewing
and printing of PDF files.
Acrobat and Reader are widely used as a way to present information with
a fixed layout similar to a paper publication.
