+#HDF5 Plots: Save/replay plots to/from HDF5
+#-------------------------------------------------------------------------------
+
+#==Usage
+===============================================================================
+Write to .hdf5 file using:
+    p = plot(...)
+   Plots.hdf5plot_write(p, "plotsave.hdf5")
+
+Read from .hdf5 file using:
+    pyplot() #Must first select backend
+    pread = Plots.hdf5plot_read("plotsave.hdf5")
+    display(pread)
+==#
+
+
+#==TODO
+===============================================================================
+ 1. Support more features
+    - SeriesAnnotations & GridLayout known to be missing.
+ 3. Improve error handling.
+    - Will likely crash if file format is off.
+ 2. Save data in a folder parallel to "plot".
+    - Will make it easier for users to locate data.
+    - Use HDF5 reference to link data?
+ 3. Develop an actual versioned file format.
+    - Should have some form of backward compatibility.
+    - Should be reliable for archival purposes.
