fixed bug in save(), now blocks containing whitespaces
will be saved using quotes, in addition the parser observes
the quoting feature, added portion about this to the pod
doc. pointed out by Jeff Murphy jcmurphy@jeffmurphy.org.added internal list of files opened so far to avoid
reading in the same file multiple times.
Suggested by Michael Graham.added new method files() which returns the above list.
added workaround for foolish perl installation on
debian systems (croak() doesn't work anymore as of
5.8.4, it's a shame!)applied patch by Michael Graham which fixes IncludeRelative
feature, now an included file is being included relative
to the calling config file, not the first one.added 'make test' targets for files() and include
stuff. (by Michael too)
