Replace Tags list lets you define your
own set of replacement rules. Due to technical reasons, you cannot
replace short tags with longer ones, for example, you can replace
STRONG with B, by
entering STRONG=B entry, but you cannot
replace B with STRONG.
Single Tags list tells the program for
which tags end tags are forbidden in the document type definition.
This information helps the program to operate more efficiently,
although optimization will work correctly even without it.
Preformatted text markup tags list tells
the program about content of which tags should be excluded from
neighboured whitespace reduction optimization.
Non-HTML Content list tells the program
content of which tags should be treated as a non-HTML. Do not
forget to define all such tags, if you do not want your scripts and
stylesheets to be accidentally optimized and broken.
Block Tags list tells the program around
which tags whitespaces can be safely removed. The program, however,
will work even without this information.
