Unzipping PSMSL Data and Documentation Files

All of the files ending in .zip have been made using the Unix zip utility with the -l option. This adds CR characters to the ends of each line of each of the files which make up the zipped bundle, so making the ends into CR LF sequences that DOS users need.

The zip files can be unbundled under DOS using a utility such as PKUNZIP. Under Unix, the unzip utility should be used with the -a option. This will strip off the CR LF sequences and convert the files back to Unix form.
