Hi there!
Well regarding the effort to replace that line with the $Author$
this should be relativ small what you need to do is:
1.) Analyse file types and the comments contained therein and decided
what you want to replace how
e.g for C++ and java we need to replace a line like
* last change: $Author: hr $ $Date: 2007/06/27 20:04:02 $
with a line containing just
*
in all .cxx, .hxx and .java files.
2.) Create a perl regular expression to do that replacement
eg. for the above C++ and java case and probably likely suitable for
some other cases as well that could be
s/(^.*)(last change:\s*)(\$Author.*\$)(.*$)/$1$4/g
3.) find all files of those certain filetypes and combine with perl
program to do the replacement.
3.1) Example for the java and C++ case
(note the below is just one commandline which is wrapped to multiple
lines by the mailer )
find . -name \*.hxx -o name \*.cxx -o -name *\.java | xargs perl -pi
.bak -e 's/(^.*)(last change:\s*)(\$Author.*\$)(.*$)/$1$4/g';
3.1.2) after checking that everything went well remove backup files
created in the step before
find . -name \*.bak | xargs rm
3.2.) If the above done in 3.1 blasts the shells commandline limit due
to two much files found either use the find -e option instead of using
xargs or apply per module instead of applying at once to the whole
source code or similar.
4.) cvs commit your changes on a childworkspace and get that integrated
Kind regards,

Hi Heiner,
A reason to drop at least the $Author$ field from the legal headers,
to avoid confusion? (I wonder, anyway, why RCSs are designed and
used in a way where the RCS modifies the stored content---expanding
$...$ fields---, as that cannot work in general.)
Yes, yes please let's do this. And while we are at it, let's remove
the other $keywords$ as well. They really do make merges more
complicated, without adding much of a value.
In fact, with our current working style, those keywords are rather
useless - unless you work in a CWS, on a file which has been altered in
this CWS before, the "$author$", "$date$" etc. information is wrong,
anyway (since it refers to the integration of the CWS where this file
was previously changed).
I'm in for removing it (spares me this "-kk" switch everytime I want to
see what really happened in a file, to suppress the disturbing keyword
diffs).
But do we really want to touch all headers in all the files in all our
modules?
Whoever did the "drop SISSL" cleanup might know how much work such a
change really is.
Now, who wants to pick this up? (I'm out, I'll be on vacation for the
next couple weeks :)
Ideally, we would also completely disable that expansion feature in the
CVS settings (whatever kind of work that means exactly), right?
