This command generates binary patches between NAR files listed in

OLD-MANIFEST and NEW-MANIFEST. The patches are written to the

directory PATCH-DIR, and the prefix PATCH-URI is used to generate URIs

for the patches. The patches are added to NEW-MANIFEST. All NARs are

required to exist in NAR-DIR. Patches are generated between

succeeding versions of packages with the same name.

.Sh DESCRIPTION
|
|
||||||
.Nm
|
|
||||||
compares
|
|
||||||
.Ao Ar oldfile Ac
|
|
||||||
to
|
|

.Ao Ar newfile Ac
|
|

and writes to

.Ao Ar patchfile Ac
|
|
||||||
a binary patch suitable for use by bspatch(1).
|
|
||||||
When
|
|
||||||
.Ao Ar oldfile Ac
|
|
||||||
and
|
|
||||||
.Ao Ar newfile Ac
|
|
||||||
are two versions of an executable program, the
|
|
||||||
patches produced are on average a factor of five smaller
|
|
||||||
than those produced by any other binary patch tool known
|
|
||||||
to the author.
|
|
||||||
.Pp
|
|
||||||
.Nm
|
|
||||||
uses memory equal to 17 times the size of
|
|
||||||
.Ao Ar oldfile Ac ,
|
|

and requires
|
|
||||||
an absolute minimum working set size of 8 times the size of oldfile.

is a binary patch built by bsdiff(1).

plus the size of

of performance.
