+version: 0.2.1.9000
+abstract: '''MTrackJ'' is an ''ImageJ'' plugin for motion tracking and analysis (see
+  <https://imagescience.org/meijering/software/mtrackj/>). This package reads and
+  writes ''MTrackJ Data Files'' (''.mdf'', see <https://imagescience.org/meijering/software/mtrackj/format/>).
+  It supports 2D data and read/writes cluster, point, and channel information. If
+  desired, generates track identifiers that are unique over the clusters. See the
+  project page for more information and examples.'
