+=item RPMVERIFY_ALL
+
+A full mask that will match any tested C<RPMVERIFY_*> value
+(except B<RPMVERIFY_NONE>).

+
+An empty mask that will not match any tested verification flags.
+
+=item RPMVERIFY_FILESIZE
+
+Test the file size against the value in the header.
+
+=item RPMVERIFY_GROUP
+
+Test the file group ID against the value it should have been set to.
+
+=item RPMVERIFY_LINKTO
+
+If the file was to be a symbolic link, check that it is set correctly.
+
+=item RPMVERIFY_MD5
+
+Check the MD5 checksum for the file.
+
+=item RPMVERIFY_MODE
+
+Verify the file mode against the value it was to be set to.
+
+=item RPMVERIFY_MTIME
+
+Check the file modification-time against that which it should have been set.
+
+=item RPMVERIFY_RDEV
+
+Check the device field of the inode, if relevant.
+
+=item RPMVERIFY_USER
+
+Check the user ID to which ownership was set.

+
+When the verification of a given file fails, the return value contains the
+relevant bits from the values above, corresponding to what test(s) failed.
+In addition, any of the following may be set to indicate a larger problem:
