The reason is, that a LaTeX formula can contain the characters "<" and "&" which have a special meaning in SGML. This little package defines four control sequences to circumvent the restriction: \lt < (less than) \gt > (greater than) \amp \& (ampersand sign) \clmn & (column separator) \gt is only provided for aesthetical reasons; the asymmetry between \lt and > looks ugly to the author of this package. The usual catcodes for >, <, and & are assumed while the package is read in. The following little sed script will make all your TeX formulae SGML #PCDATA s/</\\lt /g s/>/\\gt /g s/\\&/{\\amp}/g s/&/\\clmn /g Fine print Note the spaces inserted after \lt,\gt, and \clmn: They guarantee that the control words are ended properly. There shouldn't be any spaces eaten up, since ">" and "<" are not intended to be input in text (horizontal) mode. With standard TeX fonts they produce surprising results anyway. Leading spaces after a column separator are ignored by TeX, so no problem here. Turning the control symbol \& into a control word \amp may cause the loss of significant spaces, therefore the additional group here. The group should cause no harm, since \& is alreday of math type "other". It may suppress a hypothetical ligature or kern between the ampersand sign and a following character in text mode depending on how many passes TeX needs in order to typeset the paragraph. The standard TeX fonts don't contain such ligatures or kerns.
