		// this thing can both upload and download files so let's be careful about this
		// the upload is simple, it's just text that is handled by the AUTOCAL, so doing anything malicious isn't more likely than with any other package
		// download is iffy, because we take text from the server, fully user-definable, and save it to disk. it's stored as a txt so accudentally running it
		// or getting it to run itself, should it be a malicious script, is unlikely. still, we want to minimized the chances as much as we can
		// option 1: set file attribute to disallow running (i.e. disable executable perm)
		// option 2: add fluff that would break scripts, however they might work. we can't change the actual lines because we want the script to be edited,
		//           but we can add some extra crap that would either halt common scripting langs entirely or at least disrupt them into not functioning
		// option 3: enforce validation so only MS-ES1 script can be received by the client. this means that info such as comments or incorrectly written commands
		//           are lost, however this is the safest way because it becomes impossible to send malicious code, but it also interferes with regular user operation more
