11  Notes  New in this version
12  -----  -------------------
13  - I only tested it with:  
14          * RedHat Linux 6.[12] and 7.0  - Add patch from Henrik Carlqvist <henca@users.SourceForge.net>
15          * cvs-1.10          * add option rev_hidenumber for disabling revision number display.
16          * rcs-5.7          * add option tag_ignore_merge for disabling merge_from/merge_to display
17          * gd-1.3 and gd-1.8            if matched with tag_ignore.
18  - CvsGraph generates only gifs for old versions of gd and only png and jpeg for          * add resorting of branches on how many revisions they have. This saves
19    newer version of gd.            space under circumstances.
20    
21    - Add option merge_findall so that merge_from/merge_to tags can have multiple
22      matches.
23    
24    - Add the patches supplied by Ville Skytta <ville.skytta@iki.fi>
25            * fix spelling in the manpages and config file
26            * fix & -> &amp; problem in config
27            * fix generics in wrapper example
28    
29    - Add a fix for the zimezone problem as suggested by Henrik Carlqvist
30      <henca@users.SourceForge.net> by using the environment.
31    
32    - Fix a bug in the detection of branch-numbers in the logical ,v file structure
33      (reported by Daniel Dumitrache <ddumitrache@bitdefender.com>). The branch was
34      deduced from the revision, but that would fail for revision numbers that are
35      like magic branch-numbers (x.x.0.x) because they were interpreted. These
36      revision numbers are now correctly handled.
37    
38    - Added patch from Gordon Hollingworth <Gordon.Hollingworth@TTP.com> to use
39      mergepoints as implemented by CVSNT. Adapted the patch to enable both
40      tag-detected merges and mergepoints to be shows at the same time.

56    
57    NOTE:   The GD library is required for CvsGraph to function. Get it from
58            http://www.boutell.com, compile it and use either --with-gd-lib=DIR
59            and --with-gd-inc=DIR to specify its location. You might also have
60            to use --with-z-inc, --with-z-lib and --with-png-inc, --with-png-lib
61            for gd versions 1.6 and higher.
62            If you build with static libgd (i.e. libgd.a) and already have
63            libpng.so and/or libjpeg6b.so (i.e. dynamic), then you might want to
64            try to trick configure into adding these libs to the tests by adding
65            commandline options '--with-png-lib=.' and '--with-jpeg-lib=.'.
66            If you have linked libgd with freetype, then you might also need
67            either --with-freetype-lib or --with-freetype2-lib.
68    
69    There are often precompiled binaries for Linux, FreeBSD, NetBSD and Windows
70    (and probably other OSes too). Check your local mirror for details. I also have
71    some links on the homepage for precompiled binaries. Please do not complain to
72    me about these binaries.

105    Just to make it clear:  You cannot make images from a cvs-repository over the
106                            internet as if you were using cvs. The repository files
107                            must be on a locally mounted filesystem. However, you
108                            can use cvsup or rsync to get a repository to your
109                            local filesystem and make then images from there.

 - use ImageMagick for better control over what is generated (also multiple  
   output formats would be possible)  
 - find a way to use cvs directly instead of rcs (rlog) without the need for a  
   full checkout of the repository/module  
 - clean up the mess of finding revisions, tags and branches. The main branch  
   does not nessecarily start with revision 1.1
