RFS: [QA upload] snowdrop
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hello,
I'm seeking a sponsor for a QA upload of the package snowdrop. Snowdrop
is orphaned since over two years but in rather good shape and still
usable. I updated it to more recent Debian improvements (dh 8, quilt 3.0
package, ...), fixed some minor bugs and brought it up to date in general.
Upstream development stopped long time ago, but as it is still useful
I'd love to see this package well-kept.
I did:
* Switch to 3.0 (quilt) format, moved all changes to the upstream source
to a quilt patch
* Pushed debhelper to v8
* Switched debian/copyright to DEP-5
* Fixed some minor bugs (see changelog)
* Moved (Debian) man page out of the upstream source to debian/
* Made Lintian (mostly) happy, I didn't bother about a watch file, since
this makes no sense.
The full list of changes is attached in diff below. Joey, if you care
enough I can push you my changes to your git repository (or rather
export it somehow to you, since I have no write permissions to your
repository)
Finally I hope I didn't bother debian-qa@ too much with this request,
but last time I was told I shall CC you for QA-RFS mails.
The package can be found on mentors.debian.net:
- - URL: http://mentors.debian.net/debian/pool/main/s/snowdrop
- - Source repository: deb-src http://mentors.debian.net/debian unstable
main contrib non-free
- - dget
http://mentors.debian.net/debian/pool/main/s/snowdrop/snowdrop_0.02b-9.dsc
I'd be glad if someone could sponsor this QA upload.

+.SH DESCRIPTION
+snowdrop is a stenographic text watermarking and watermark recovery system.
+It is composed of three programs:
+.TP
+.B sd-eng
+Watermark normal English text.
+.TP
+.B sd-engf
+Watermark fine quality English text, yeilding higher quality output but
+encoding less information.
+.TP
+.B sd-c
+Watermark C code.
+.P
+The three programs operate similarly, with the same parameters and usage. The
+watermark is encoded in using a number of techniques, such as whitespace
+reformatting, typo insertation, word substitutions, punctuation changes,
+and for C code, logic reordering, variable name mangling, etc.
+.P
+The watermark is a md5sum, which is retreivable from as little as
+5 or 10 lines of the watermarked document. Even large changes to a medium
+sized document should not obscure the watermark, as it is stored redundently
+in multiple independent channels.
+.P
+The three usage modes are adding a watermark, checking for the presense of a
+watermark, and listing the contents of your database of watermarks. Note
+that to later check a watermark, you must retain a copy of the original,
+un-watermarked file.
+.SH OPTIONS
+.TP
+.B -i
+Inject a watermark into a file. You must pass it the original file, the
+filename to output the watwrmarked version to, information about who
+you intend the watermarked file for, and an optional comment.
+.TP
+.B -e
+Extract a watermark from a file. Needs the original file
+and the new file that you suspect bears the watermark.
+.TP
+.B -l
+Lists the contents of the watermark database. Each of the three programs
+will have a different list.
+.TP
+.B -6
