29 @brief This task creates fake alignment.
30 Which alignment, depends on the bit mask passed to the
31 constructor, or added by `AddAlign'.
33 The default is to write all alignment parameters to a local
34 storage @c local://cdb which is a directory in the current
38 class AliFMDAlignFaker : public TTask
