NAME
bk filetypes − summary of BitKeeper file types

DESCRIPTION
For each file under revision control, there are a number of files associated with the main file. The following list describes the purpose of each file:
foo “gfile” − the “gotten” file; this is your source file
SCCS/s.foo “sfile” − the revision history of all versions of the gfile
SCCS/x.foo “xfile” − a temporary file which contains the new version of the sfile under construction. When the check-in is finished, the sfile is removed and the xfile is moved into its place.
SCCS/c.foo “cfile” − a temporary copy of check in comments, currently used only by bk citool.
SCCS/d.foo “dfile” − a temporary file that indicates there is at least one pending delta in the sfile.

FUTURE DIRECTIONS
Other than the gfile, accessing any of these files directly is discouraged. In the future, all of the meta-files will be virtual. At that point, there will be interfaces to read them, test for their presence, and write them.
