+The mandi package  provides commands  for typesetting symbols, expressions, and
+quantities used in introductory physics and astronomy. Many of the commands are
+inspired by  Matter & Interactions  by Ruth Chabay  and Bruce Sherwood. Many of
+the  astronomical commands  were inspired by my own classroom needs. It must be
+understood that mandi does  not do any  computations! It only provides commands
+for typesetting.
+
+Run  the  file  mandi.dtx  through (pdf)LaTeX  to  generate README (this file),
+mandi.ins, mandi.sty,  vdemo.py,  and  mandi.pdf (user documentation). I assume
+a TeXLive2011 or later distribution is installed.
