In looking at the bam I'm not sure I understand how I could use it.

My current routes are generated dynamically and equate to something of the
following form:

from("ftp://"; ) - set GenericFileExclusiveReadLockStrategy for done file
handling
   .to( stepA )

   .to( .... )

If I create an ActivityBuilder on the route, at what step would I tell the
bam to fire?  THe GenericFileExclusiveReadLockStrategy will prevent the file
from appearing until the file is available so the bam won't have a message /
instance to trigger on.
