C++ include file with revision id

[guerinp at magic.fr]

Hello John,

It's the way I do to produce my include file

    #!/bin/sh
    nickname=`bzr version-info --custom --template="{branch_nick}"`
    bazaar_revid=`bzr version-info --custom --template="{revision_id}"`
    echo "#define `echo ${nickname}_revid|tr '[:lower:]' '[:upper:]'` 
    \"${bazaar_revid}\"" > include/${nickname}_manifest.h

For now this file is generated after the commit was done.
But as the file is not versionned and generated in the working directory 
and thus imply the following
1/ "commit --strict" gives an error if this file is not versionned or 
ignored
2/ "bzr export" does not take this file in account because it's not 
versionned though it is necessary to have a complete standalone release.

I already have modified, as a plugin, the export command to use the 
commit timestamp instead of the current time
by replacing "now" by "mtime" in the exporter functions where
    mtime = tree.get_file_mtime(ie.file_id)
Is it possible to access to this file in the working tree inside the 
exporter functions to include it in the archive ?

Kind regards
Patrice.
