That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (ce69474de3375928b3bd460111356d419f6a966c) \ N -- N -- N (a6a8d2a44d746824876f24c53af69f83036ddaf3) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- a6a8d2a src/README: New. 810f041 configure.ac: configure several directories in scribo/. 33ffff6 Improve Scribo demo. 31216d3 Small fixes. db55e63 Add the binarization tool submitted to H-DIBCO 2010. 080134d Update tools in scribo/src. 40d5180 Add a specific toolchain for Nepomuk integration. cbbdf4e Cleanup sample tools. ff15d07 toolchain/text_in_doc.hh: Introduce a new routine for extracting text in a document. 12ddb97 core/def/lbl_type.hh: Introduce a global label type. b8aaeba Improve line detection. cbbbffd io/text_boxes/save.hh: New.
