* un-escaped use of < and > in a 'pre' element * confusion about nesting of p and ul/ol/pre/blockquote elements * confusion about nesting of li and ul elements * added p elements around completely naked text * escaped naked < > and & characters * removed dangling </li> </div> and </h4> tags * clean up weird auto-generated HTML - paragraph boundary weirdness - a display div was being used where a <dl> was best * removed unnecessary whitespace * changed a pre element which was apparently intended to be inline to a tt element which is actually inline not block.
* fix bad spelling * use American spellings (e.g. analyze vs analyse) * don't introduce artificial sentence breaks for "i.e." and "e.g." * use the definite and indefinite articles more appropriately * various other minor grammar fixes * remove one copy of a duplicated paragraph
