-# History:
-# 2002-08-23 created by Peter Oberparleiter <Peter.Oberparleiter@de.ibm.com>
-# IBM Lab Boeblingen
-# based on code by Manoj Iyer <manjo@mail.utexas.edu> and
-# Megan Bock <mbock@us.ibm.com>
-# IBM Austin
-# 2002-08-27 / Peter Oberparleiter: implemented frame view
-# 2002-08-29 / Peter Oberparleiter: implemented test description filtering
-# so that by default only descriptions for test cases which
-# actually hit some source lines are kept
-# 2002-09-05 / Peter Oberparleiter: implemented --no-sourceview
-# 2002-09-05 / Mike Kobler: One of my source file paths includes a "+" in
-# the directory name. I found that genhtml.pl died when it
-# encountered it. I was able to fix the problem by modifying
-# the string with the escape character before parsing it.
-# 2002-10-26 / Peter Oberparleiter: implemented --num-spaces
-# 2003-04-07 / Peter Oberparleiter: fixed bug which resulted in an error
-# when trying to combine .info files containing data without
-# a test name
-# 2003-04-10 / Peter Oberparleiter: extended fix by Mike to also cover
-# other special characters
-# 2003-04-30 / Peter Oberparleiter: made info write to STDERR, not STDOUT
-# 2003-07-10 / Peter Oberparleiter: added line checksum support
-# 2004-08-09 / Peter Oberparleiter: added configuration file support
-# 2005-03-04 / Cal Pierog: added legend to HTML output, fixed coloring of
-# "good coverage" background
-# 2006-03-18 / Marcus Boerger: added --custom-intro, --custom-outro and
-# overwrite --no-prefix if --prefix is present
-# 2006-03-20 / Peter Oberparleiter: changes to custom_* function (rename
-# to html_prolog/_epilog, minor modifications to implementation),
-# changed prefix/noprefix handling to be consistent with current
-# logic
-# 2006-03-20 / Peter Oberparleiter: added --html-extension option
-# 2008-07-14 / Tom Zoerner: added --function-coverage command line option;
-# added function table to source file page
-# 2008-08-13 / Peter Oberparleiter: modified function coverage
-# implementation (now enabled per default),
-# introduced sorting option (enabled per default)
