tools for deleting the expanded $Log$ comments

[David]

Hello members,

I would like to know if there is a tools (in perl for example) that delete
all the $Log$ expanded comments. Sometimes it is usefull because your
classes have revisions for a given project, but if you decide to eliminate
from all your code the inserted log comments for a given new revision, or
because your are using your class on another project.

Do you have any suggestion about how to handle such situation. For example I
would like to replace the expanded comments by $Log$, becase I wanto to use
such source files on another project.

Thanks in advance,

David
