Sirius has evolved into becoming an enormous resource for solving many problems that you may encounter in astrology and sometimes outside of astrology. A new feature for merging columns in columns in two or more text files was added while we were conducting research on Gauquelin sectors and we wanted to merge results from several different analyses into one file. Rather than find a program to do this, we added this feature to Sirius.
We also added a feature to compress files into a zip file because the programs to zip files that are available by download over the Internet sometimes have restrictions and limitations and the process of finding such programs and installing them can be onerous so we added the ability to compress files. We did NOT add the feature of unzipping a zip file.
