The bzr-keywords plugin provides that: https://launchpad.net/bzr-keywords

An alternative way to generate that is the 'bzr version-info' command.
For example:

    bzr version-info --custom --template='const char * revno="{revno}";\n' > revno.c

See 'bzr help version-info' for more details (and more detailed
examples).

Keyword expansion in files is a bit unnatural in that bzr versions the
whole tree together, rather than independent individual files.  Stamping
a file with the revision it was last changed doesn't imply much about
the state of the rest of the source tree.

Yep, bzr-keywords.

If what you want is to automate having the bzr revision details stamped
in your code as part of the build process, you're probably better off
with something like a 'bzr version-info ... > foo.c' step in your build
script.
