utils package and manually fixed some places where perltidy's reformatting made it harder to read. the options used were-- -i=4 # 4-space indentation -l=0 # unlimited line length (for now) -pt=2 # slightly tightened parens -ce # cuddled elses -nolq # don't outdent long quotes -nsfs # don't add spaces in front of semi-colons in for ( ) statements -isbc # only indent block comments that have whitespace in front of them -otr # don't place a break between a comma and an opening brace the code will be refactored to make it possible to switch to using 80-column line-breaks without resorting to really nasty formatting constructs.
