Introduction
In this tutorial we learn how to install psgml on Ubuntu.
What is psgml
psgml is:
PSGML is a major mode for the editor Emacs used for editing SGML documents. It contains a simple SGML parser and can work with any DTD. (The most popular nowadays are the HTML DTDs. This package turns your emacs into the one of most powerful HTML editors and will be ultimately flexible as well, since you could upgrade your editor by just installing new DTDs). Functions provided includes menus and commands for inserting tags with only the contextually valid tags, identification of structural errors, editing of attribute values in a separate window with information about types and defaults, and structure based editing.
Since psgml parses the DTD to allow you to edit SGML documents, you do need to have the DTDs installed in order to use psgml. Since psgml installs itself as an HTML mode in Emacs, it depends on sgml-data. Some other packages which also provide SGML DTDs are suggested, like debiandoc-sgml and linuxdoc-sgml.
SGML, a language for encoding the structure of a document, is an ISO standard: ISO 8879:1986 “Information processing - Text and office systems - Standard Generalized Markup Language (SGML)”.
Psgml is a standard package for XEmacs, and thus this package does not install itself for XEmacsen.
The official home page has not been updated since 2005. The latest version of this package was built from an unofficial version at URL:http://www.fsavigny.de/gpled-software/psgml-1.4.0.tar.gz
