-=item hash_object ( TYPE, FILENAME )
+=item ident ( TYPE | IDENTSTR )
+
+=item ident_person ( TYPE | IDENTSTR | IDENTARRAY )
+
+This suite of functions retrieves and parses ident information, as stored
+in the commit and tag objects or produced by C<var GIT_type_IDENT> (thus
+C<TYPE> can be either I<author> or I<committer>; case is insignificant).
+
+The C<ident> method retrieves the ident information from C<git-var>
+and either returns it as a scalar string or as an array with the fields parsed.
+Alternatively, it can take a prepared ident string (e.g. from the commit
+object) and just parse it.
+
+C<ident_person> returns the person part of the ident - name and email;
+it can take the same arguments as C<ident> or the array returned by C<ident>.
+
+The synopsis is like:
+
+ my ($name, $email, $time_tz) = ident('author');
+ "$name <$email>" eq ident_person('author');
+ "$name <$email>" eq ident_person($name);
+ $time_tz =~ /^\d+ [+-]\d{4}$/;
+
+Both methods must be called on a repository instance.

-=item hash_object ( TYPE, FILEHANDLE )
+
+=item hash_object ( TYPE, FILENAME )
Compute the SHA1 object id of the given C<FILENAME> (or data waiting in
C<FILEHANDLE>) considering it is of the C<TYPE> object type (C<blob>,
C<commit>, C<tree>).
-In case of C<FILEHANDLE> passed instead of file name, all the data
-available are read and hashed, and the filehandle is automatically
-closed. The file handle should be freshly opened - if you have already
-read anything from the file handle, the results are undefined (since
-this function works directly with the file descriptor and internal
-PerlIO buffering might have messed things up).
-
The method can be called without any instance or on a specified Git repository,
it makes zero difference.
The function returns the SHA1 hash.
-Implementation of this function is very fast; no external command calls
-are involved.
