YEST SCRIPT 1.14 RELEASE - README

Features:
	This is called "yest" because  the default is to output yesterday´s
	date.  This utility knows about leap year, daylight savings time, and
	such variations.

	This utility adds or subtracts days, hours, and/or minutes from a given
	date, and outputs the result in the specified format.

	The default, if no adjustment is specified, is "-1d" (subtract one day).

	Yest supports most date(1) format codes as well as a few of its own.
	Particularly interesting is the "%L" (last day of the month) token.
	Finding the last day of the month has always been a problem in Unices.

	This is an update to the very original korn shell script.  Yest was
	rewritten in C to make it very fast and to add features.  However, I
	understand that in some environments, due to security or other factors,
	it is too difficult to install a compiled program.

	This script is, essentially, a drop-in replacement for the compiled
	version.  It may be slower, especially for larger adjustment values,
	and it is lacking the %q (daylight savings), %s (epoch seconds) and
	%Z (timezone) functions.
