Re: gtk-doc version and configure.in breakage

[Dan Mills <thunder ximian com>]

I came up with a shell version, in case anyone wants to use that
instead.  It's a straight port of the perl version below, so far it
seems to work O.K.

Here it is:

installed=`echo $gtk_doc_version | sed 's/\./ /g'`
required=`echo $gtk_doc_min_version | sed 's/\./ /g'`

for r in $required; do
    foo=`echo $installed | awk '{ print $1 }'`
    installed=`echo $installed | sed 's/^[^ ]\+ \?//'`
    if test ! -n "$foo"; then exit 1; fi

    if test "$foo" -lt "$r"; then exit 1; fi
    if test "$foo" -gt "$r"; then exit 0; fi
done

exit 0

If you want to test it by itself you can use this version:
