Also included in the s-file is some header information for each version, including the comments given by the person who created the version explaining why the changes were made. Each set of changes to the s-file is called a delta. In addition, any disk corruption are immediately discovered when the s-file is opened for processing. This is was done to consolodate the WebDAV properties and supplemental version control information in the same location. Binary content is automatically saved in binary form in the SCCS file regardless of whether flags indicate the content is binary.
Binary content is stored in compressed form.
Basically, sccs runs the command with the specified flags and args. Flags to be interpreted by the sccs program must be before the command argument. Flags to be passed to the actual SCCS program must come after the command argument. These flags are specific to the command and are discussed in the documentation for that command. The new versions will have id keywords expanded, and will not be editable.
