XThe need to provide a means of packaging useful pieces of code for easy
Xrepeated use was recognised in the very earliest programming
Xlanguages.  This need is even more acute in document formatting, if that
Xis possible, because the majority of users are not programmers and do
Xnot understand the code they invoke.

X#  This package makes extensive use of the Adobe Systems Symbol font, and     #
X#  it assumes that the font has not been recoded.  It could be rewritten      #
X#  using the @Char symbol to be made independent of any recoding, but since   #
X#  there seems no reason to ever recode this font, I haven't bothered.        #

X#  See "Eq - a Lout package for typesetting mathematics" for user             #
X#  information.  Acknowledgement:  the @Eq language is based closely on       #
X#  the Eqn language of B. W. Kernighan and L. L. Cherry; the spacing rules    #
X#  are similar to those of the TeX system by D. E. Knuth.                     #
