Last checked against version &texinfo-contversion;. info, infokey, install-info, makeinfo, texi2dvi and texindex The info program reads Info documents, usually contained in the /usr/share/info directory. Info documents are like man(ual) pages, but they tend to go deeper than just explaining the options to a program. infokey compiles a source file containing Info customizations into a binary format. The install-info program updates the info entries. When the info program is run, a list with available topics (ie: available info documents) will be presented. The install-info program is used to maintain this list of available topics. If info files are removed manually, you must also delete the topic in the index file. This program is used for that. It also works the other way around when info documents are added. The makeinfo program translates Texinfo source documents into various formats. Available formats are: info files, plain text and HTML. The texi2dvi program prints Texinfo documents. The texindex program is used to sort Texinfo index files.
