+QPDF is a program that does structural, content-preserving
+transformations on PDF files.  It could have been called something
+like pdf-to-pdf.  It also provides many useful capabilities to
+developers of PDF-producing software or for people who just want to
+look at the innards of a PDF file to learn more about how they work.
+
+QPDF offers many capabilities such as linearization (web
+optimization), encrypt, and decription of PDF files.  Note that QPDF
+does not have the capability to create PDF files from scratch; it is
+only used to create PDF files with special characteristics starting
+from other PDF files or to inspect or extract information from
+existing PDF files.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
