Bugzilla Bug 29731

Diffball is a differencing suite I've been working on for a while, supporting
multiple binary patch formats (xdelta, bdelta, bdiff, gdiff4...), and w/
preliminary unified gdiff support, and easy framework for supporting
compression, and dropping new formats/algs in.
Since diffball functions as a binary differencer, it's patches produce md5
correct reconstructed files.  My intention, is to base distfile diff'ing upon
it- at the very least it's a rather useful utility (imho).

While diffball has just had it's initial release (2 days ago as of this
message), it's been in development for 4 months, working for 3 out of the 4.
I'm confident in it's stability, the only detractor is documentation- it has an
appropriate set of man files, although I do need to make them less spartan,
write out out the Readme, and add the remaining 0.4 features (detailed in the
TODO file).
Suggested location being sys-apps/diffball, although that's only my peon level
suggestion...
thanks, bdh

Suggestions for dealing w/ the extra pre portion of the version would be
welcome...

Complaints about strnlen, and make failures regarding libmath functions (sqrt
for instance) have been resolved as of diffball-0.4_pre2.
Diffball is currently at 0.4_pre3, and I'll be updating this ebuild once
0.4_pre4 is released (which is planned for/around 10/31/2003).

In general, the updates since the initial pre-0.40 release have been cleaning
it up for general usage, lessening memory req's, optimizing worst run conditions,
etc.  0.4_pre4 will likely become the actual 0.40 release.

v0.4_pre4 ebuild

renamed ebuild for 0.4_pre4

Renamed ebuild for v0.4_pre4, the most current version of diffball.
Best to use this version, rather then earlier pre{2,3}, since this is the
culmination of fixes, run-time improvements, and general cleanup.

Basically in need of user testing.

fixed SRC_URI, no other change.

fixed a rather dumb mistake in the src_uri .
Now points to the correct location.

added to portage
