xyconv is a simple utility that converts files in formats supported
by xylib into TSV (tab-separated-values) format.
Xylib library supports a subset of Vamas ISO14976 format, several formats
used for storing data from powder diffraction (pdCIF, Bruker RAW and UXD,
Philips RD and UDF, Sietronics Sieray CPI) and other niche formats,
typically containing 1D data from physical or chemical experiments.
