            == Java GIT ==

This package is licensed under the BSD.

org.eclipse.jgit/

A pure Java library capable of being run standalone, with no
additional support libraries. Some JUnit tests are provided
to exercise the library. The library provides functions to
read and write a GIT formatted repository.

All portions of jgit are covered by the BSD. Absolutely no GPL,
LGPL or EPL contributions are accepted within this package.

org.eclipse.jgit.test/
Unit tests for org.eclipse.jgit and the same licensing rules.

== WARNINGS / CAVEATS ==

- Symbolic links are not supported because java does not support it.
Such links could be damaged.

- Only the timestamp of the index is used by jgit check if the index
is dirty.

- Don't try the library with a JDK other than 1.6 (Java 6) unless you
are prepared to investigate problems yourself. JDK 1.5.0_11 and later
Java 5 versions *may* work. Earlier versions do not. JDK 1.4 is *not*
supported. Apple's Java 1.5.0_07 is reported to work acceptably. We
have no information about other vendors. Please report your findings
if you try.

- CRLF conversion is never performed. On Windows you should thereforc
make sure your projects and workspaces are configured to save files
with Unix (LF) line endings.

== Package Features ==

org.eclipse.jgit/

* Read loose and packed commits, trees, blobs, including
deltafied objects.

* Read objects from shared repositories

* Write loose commits, trees, blobs.

* Write blobs from local files or Java InputStreams.

* Read blobs as Java InputStreams.

* Copy trees to local directory, or local directory to a tree.

* Lazily loads objects as necessary.

* Read and write .git/config files.

* Create a new repository.

* Read and write refs, including walking through symrefs.

* Read, update and write the Git index.

* Checkout in dirty working directory if trivial.

* Walk the history from a given set of commits looking for commits
introducing changes in files under a specified path.

* Object transport
Fetch via ssh, git, http, Amazon S3 and bundles.
Push via ssh, git and Amazon S3. JGit does not yet deltify
the pushed packs so they may be a lot larger than C Git packs.

org.eclipse.jgit.pgm/

* Assorted set of command line utilities. Mostly for ad-hoc testing of jgit
log, glog, fetch etc.

== Missing Features ==

There are a lot of missing features. You need the real Git for this.
For some operations it may just be the preferred solution also. There
are not just a command line, there is e.g. git-gui that makes committing
partial files simple.

- Merging.

- Repacking.

- Generate a GIT format patch.

- Apply a GIT format patch.

- Documentation. :-)

- gitattributes support
In particular CRLF conversion is not implemented. Files are treated
as byte sequences.

- submodule support
Submodules are not supported or even recognized.

== Support ==

Post question, comments or patches to the git@vger.kernel.org mailing list.


== Contributing ==

See SUBMITTING_PATCHES in this directory. However, feedback and bug reports
are also contributions.
