+# ========
+#
+# This script is a joint effort of
+# Dag Langmyhr, Department of Informatics, University of Oslo
+# (dag at ifi.uio.no)
+# and
+# Hironobu Yamashita, Japanese TeX Development Community
+# (h.y.acetaminophen at gmail.com)
+#
+# A program to print information about a DVI file.
+#
+# Usage: dviinfox [options] file1 file2 ...
+# where the flags indicate which information is desired.
+# -f Give information about the fonts used.
+# -p Give information about the number of pages.
+# -v List the program version number.
+# -h Show help message.
+# No options will provide all information available.
+#
+# Example:
+# % dviinfox alltt.dvi
+# alltt.dvi: DVI format 2; 3 pages
+# Magnification: 1000/1000
+# Size unit: 1000x25400000/(1000x473628672)dum = 0.054dum = 1.000sp
