Checked the v0.1 under win32 and Scilab 5.3.2:

-->atomsInstall('imsls')
 ans  =
!imsls  0.1-2  allusers  SCI\contrib\imsls\0.1-2  I  !
-->atomsLoad('imsls')
Start Imsls
	Load macros
	Load help
	Load demos
	Type "help imsls_overview" for quick start.
 ans  =
!imsls  0.1-2  allusers  SCI\contrib\imsls\0.1-2  !

All tests pass.
