preliminary instructions for the windows command line version of shalstab
-------------------------------------------------------------------------

- copy winstab.zip to your c:\shalstab directory
- extract the files (reply yes to any overwrite dialog)
- click start->run and type "cmd" in the "open" dialog
- type "cd \shalstab" to change to the working directory
- run the program as follows:
	1) type shalstab to get instructions
	2) for one-step shalstab with the little coos bay grid use the following command:
		shalstab coos.asc 1700 45 > coosstab.asc
	3) to write all the intermediate grids use the following command
		shalstab coos.asc 1700 45 0 coosrem.asc coosslope.asc coosab.asc > coosstab.asc
- several other programs and utilities are provided, typing their name will provide help
	1) arc2surf: converts an arcinfo ascii grid to a surfer ascii grid
	2) area: computes A/b
	3) curvature: computes total curvature
	4) qovert: computes q/T from slope and area grids
	5) qovertcf: computes q/T from slope and area grids with cohesion and soil depth
	6) removesinks: removes sinks from a grid
	7) slope: computes slope on a 3x3 cell neighborhood
	8) testsinks: will scan a grid and check for sinks	
	9) surf2arc: converts a surfer ascii grid to an arcinfo ascii grid
