DESCRIPTION
-----------
<object>::
An object to treat as the head of an unreachability trace.

-If no objects are given, git-fsck defaults to using the
+If no objects are given, 'git fsck' defaults to using the
index file, all SHA1 references in .git/refs/*, and all reflogs (unless
--no-reflogs is given) as heads.
--unreachable::
- Print out objects that exist but that aren't readable from any
+ Print out objects that exist but that aren't reachable from any
of the reference nodes.
+--dangling::
+--no-dangling::
+ Print objects that exist but that are never 'directly' used (default).
+ `--no-dangling` can be used to omit this information from the output.
+
--root::
Report root nodes.

+ with --no-full.
--strict::
Enable more strict checking, namely to catch a file mode
a blob, the contents are written into the file, rather than
its object name.
-It tests SHA1 and general object sanity, and it does full tracking of
-the resulting reachability and everything else. It prints out any
-corruption it finds (missing or bad objects), and if you use the
-'--unreachable' flag it will also print out objects that exist but
-that aren't readable from any of the specified head nodes.

-So for example
+--progress::
+--no-progress::
+ Progress status is reported on the standard error stream by

+ --no-progress or --verbose is specified. --progress forces
+ progress status even if the standard error stream is not
+ directed to a terminal.

+DISCUSSION
+----------
-will do quite a _lot_ of verification on the tree. There are a few
-extra validity tests to be added (make sure that tree objects are
-sorted properly etc), but on the whole if "git-fsck" is happy, you
-do have a valid tree.

-(i.e., you can just remove them and do an "rsync" with some other site in

-Of course, "valid tree" doesn't mean that it wasn't generated by some
-evil person, and the end result might be crap. git is a revision
-tracking system, not a quality assurance system ;)

Extracted Diagnostics
---------------------
The <type> object <object>, is present in the database but never
'directly' used. A dangling commit could be a root node.
-warning: git-fsck: tree <tree> has full pathnames in it::
- And it shouldn't...
-
sha1 mismatch <object>::
The database has an object who's sha1 doesn't match the
database value.
GIT_ALTERNATE_OBJECT_DIRECTORIES::
used to specify additional object database roots (usually unset)
