+# png2uri is a command-line application that creates an HTML "img" tag on
+# standard output containing a data URI, from a PNG file or from standard
+# input.
+#
+# Usage: png2uri [file]
+#
+# Requires /bin/sh and a uuencode(1) that takes the "-m" option to mean
+# to encode in base64.
+#
+# If you prefer a web-based converter or a java application, this isn't
+# it. Use your search engine and look for "png data uri" to find one.
