wpkg --clear-exceptions ...
When creating packages, your install scripts may copy unwanted files to the output directories. To avoid adding that unwanted data to the package, one can use exceptions. By default wpkg ignores a set of directories and files as defined in the --exception option. The --clear-exceptions option can be used to remove all of those exceptions. You can then use the --exception option to add your own exceptions.
IMPORTANT NOTE
It is important to understand that the --clear-exceptions can appear anywhere on the command line, all the --exception options are still effective (i.e. the --clear-exceptions doesn't clear any user defined exceptions!) To remove user defined exceptions, fix your command line.
