mcread 1.0 -- (C) 1991 by Mike Gleason Jr., NCEMRSoft.\n\
mcread can decode MacWrite, TeachText, and TEXT files, created on\n\
Apple Macintosh(tm) computers, for reading on other platforms.\n\
This is Un*x ShareWare.  If you use this tool, you can show your\n\
gratitude in one or both of the following ways:\n\
  1. Whip out a 1$US bill (or the equivalent foreign currency;\n\
     I like foreign coins) and mail it to the address below;\n\
     It's only a dollar, and it goes towards a good cause: my tuition!\n\
  2. Mail me a short note written on your company stationery saying\n\
     how useful this is to you, blah, blah, blah.  This is for\n\
     the scholarship committee here at the University of Nebraska;\n\
     If I can hand in a bunch of these letters with my scholarship\n\
     form, they'll be impressed, and maybe give me a grant!\n\
Thanks!!!\n\
