Dear all,
currently I'm using the latest version of picongpu-0.2.0 (9c6cf3c). It looks like in one of the latest commits the command line parser was changed such that an example LWFA simulation fails with a fatal error. Attached script demonstrates this behavior:
$ ./runit.sh
<...>
[1,0]<stderr>:unrecognised option '--e_png.period'
<...>

At least in c91e73e there is no such problem. Could you please take a look?

Thank you in advance,
Danila.
