&SecRef-1;SU-1Some MarkupThe following is markup under basic GELLMU for an HTML document: documenttypehtmlnewcommandh1c1h1aligncenter1newcommandqa2ahref12newcommandua1ahref11newcommandlatexemLaTeXtitleHTMLMarkedUpwithGELLMUh1cIsemThisanHTMLDocumentpAlthoughthislooksmoreorlesslikealatexdocumentitisreallyadocumentwrittenintheHTMLlanguageusinglatexlikesyntaxpThisdocumentmaybeeasilyconvertedtoanormalHTMLdocumentusingtheembasicmodeoftheGELLMUsyntactictranslatorwhichisanEmacsLispprogramavailableonthewebthroughcenteruahttpwwwalbanyeduhammondgellmupGELLMUstandsforGeneralizedExtensiblelatexLikeMarkupItsprimarypurposeistoserveasabridgeforauthorsfromlatextotheworldofXMLpThusthisusageofGELLMUisbasicallyrecreationalcomparedtoitsmoreseriouspurposeusinglatexlikemarkuptowriteforamuchricherXMLdocumenttypethanHTMLActuallythisdocumentiswrittenforoldHTMLwhichisanSGMLapplicationthatdoesnotcomeunderXMLButthereisacanonicalwaytotranslateoldHTMLtotheXMLversionofHTMLpFormoreinformationonwritingHTMLthiswayseetheshortarticleqahttpwwwalbanyeduhammondgellmughtmlhtmlemUsingGELLMUtoWriteHTMLpFormoreinformationontheseriouspurposeofGELLMUpleasevisitqahttpwwwalbanyeduhammondgellmuTheGELLMUWeb

&SecRef-2;SU-2Approximate RenderingNow follows a rendering of how the HTML should appear pagebreak Is This an HTML Document? Although this looks, more or less, like a document, it is really a document written in the HTML language using like syntax This document may be easily converted to a normal HTML document using the basic mode of the GELLMU syntactic translator, which is an Emacs Lisp program available on the web through http://www.albany.edu/hammond/gellmu/ . GELLMU stands for Generalized Extensible Like Markup Its primary purpose is to serve as a bridge for authors from to the world of XML Thus, this usage of GELLMU is basically recreational compared to its more serious purpose: using like markup to write for a much richer XML document type than HTML Actually, this document is written for old HTML, which is an SGML application that does not come under XML But there is a canonical way to translate old HTML to the XML version of HTML For more information on writing HTML this way see the short article href="http://www.albany.edu/hammond/gellmu/ghtml.html"Using GELLMU to Write HTML For more information on the serious purpose of GELLMU please visit href="http://www.albany.edu/hammond/gellmu/"The GELLMU Web

&SecRef-3;SU-3What is Going On?First observe that the verbatim section is an HTML document marked up with GELLMU It may be converted to HTML with emacsbatchlgellmuelcfgellmuhtmlhteaseglm if it is saved to the name hteaseglmThis document overall is a like document prepared for href="http://www.albany.edu/hammond/gellmu/iglm.html"regular GELLMU under the didactic GELLMU article document type, a document type that has both SGML and XML existenceIt makes extensive use of the newcommand metacommand in GELLMU, which is macro expansion with arguments Moreover, it begins by using the verbatim pseudoenvironment to present like source under basic GELLMU for an HTML document That document itself makes use of newcommandThe use of newcommand in the internal document is exported to this document using newcommand in this document, recasting HTML constructions into equivalent markup under article The source that appeared inside verbatim wraps is then used again without wrapping, and appears between horizontal rulesWhile the didactic production system for article comes with formatters for the XML version only toward the targets (1) HTML and (2) , the document type is suitable for handling by any general purpose XML processorWould someone care to format the XML version to (3) DocBook (4) SGMLTexi? (5) TEI There only about 50 tags in the XML, many of which are easy empties and a few of which should be thrown away
