all syntax to download and analyze publicly-available survey microdata confirmed to work on windows, macintosh, and unix systems

the creators of monetdb at centrum wiskunde and informatica generously provided me with a unix shell account to test out each of the scripts in the repository.  much of my code already worked across platforms, but i have finished tweaking and testing, and can confirm that every script now works without changes on all three platforms.  special thanks to hannes, our man in amsterdam.  if you want to analyze millions of records, on your personal computer, for free, in seconds, read this.
