AsciiDoc can also be used to build and maintain websites. . You write an AsciiDoc document the same way you would write a normal text document, there are no markup tags or weird format notations. AsciiDoc files are designed to be viewed, edited and printed directly or translated to other presentation formats . This package provides binary files for the package. Be careful, you won't be able to build pdf files without the dblatex or fop dependencies. See asciidoc-dblatex or asciidoc-fop metapackages for this.
