So the here is what I am trying to convert to Piston:

$ svn st plugins
X      plugins/sfHamlViewPlugin
X      plugins/sfPropelMigrationsLightPlugin
X      plugins/sfPropel13Plugin
X      plugins/sfFacebookPlatformPlugin
X      plugins/sfPropelAlternativeSchemaPlugin

Performing status on external item at 'plugins/sfHamlViewPlugin'

Performing status on external item at 'plugins/sfFacebookPlatformPlugin'

Performing status on external item at 'plugins/sfPropelMigrationsLightPlugin'

Performing status on external item at 'plugins/sfPropel13Plugin'
X      plugins/sfPropel13Plugin/lib/vendor/propel
X      plugins/sfPropel13Plugin/lib/vendor/propel-generator

Performing status on external item at 'plugins/sfPropel13Plugin/lib/vendor/propel'

Performing status on external item at 'plugins/sfPropel13Plugin/lib/vendor/propel-generator'

Performing status on external item at 'plugins/sfPropelAlternativeSchemaPlugin'


As you can see plugins/sfPropel13Plugin has svn:externals but Piston throws an error that there are local modifications
and exits.

Obviously the problem comes from this line in piston-1.4.0/lib/piston/commands/convert.rb:34

raise Piston::CommandError, "#{local_dir.inspect} has local modifications:\n#{status}\nYour must revert or commit
before trying again." unless status.empty?

Now unless there is a deeper issue of svn:externals having their own externals, this is easily fixed but again I am
not sure if there are other things that need to be taken into account.

Hope that helps,
Kiril

Hi, thanks for the bug report.  I'm working on Piston 2.0, and
will take care of this problem there.
