"""PySeq is a python module that finds groups of items that follow a naming
convention containing a numerical sequence index, e.g. ::
fileA.001.png, fileA.002.png, fileA.003.png...
and serializes them into a compressed sequence string representing the entire
sequence, e.g. ::
fileA.1-3.png
It should work regardless of where the numerical sequence index is embedded
in the name.
