#  This script is intended to be run in the build directory of a software
#  package including documentation in texinfo format.  The basic operation
#  of this script is to:
#      + find all ".dvi" files from the current directory down,
#      + for each dvi file
#        + install the dvi file 
#        + generate PostScript files for the dvi file
#        + install the PostScript file 
#        + if there is texinfo source for this dvi file
#             install the info files 
#             generate PDF from the texinfo source 
#             install the PDF file
#             generate HTML from the texinfo source 
#             install the HTML file
#
