Just to nip this in the bud. You *cannot* modify a commit transaction
with a hook script. You can only reject it.

Your best bet is to have clients use a default configuration file which
identifies the binary files you wish to use.

There is talk about a global config file, but currently it is up to each
client (on the users computer) to determine their configuration.

Depending on your OS, here is a one liner that should get you what you
want, then cut the end off and run that through xargs again to set the
need-lock property.

find . -type f | grep -v .svn | xargs svn propget "svn:mime-type" 2>/dev/null | grep application/octet-stream$

You'll get a listing like this:
ext/dom/tests/book.xml.gz - application/octet-stream
ext/xsl/tests/xslt.xsl.gz - application/octet-stream
ext/dba/tests/test.cdb - application/octet-stream

Let me explain, sections are separated by pipes `|'
1. List all the files in the current directory.
2. Filter out files in a .svn directory
3. Ask subversion if the property is set, disregard all error messages
4. Only print the files that are binary, as we could have other
mime-types.

Cheers,
Chris
