+PDF Studio Viewer is a cross-platform PDF reader that is reliable and
+easy to use. PDF Studio Viewer can annotate PDF documents and fill
+interactive forms. For more editing features, there is the pdfstudio
+package.
+
+PDF Studio Viewer is a free proprietary Java based program (while
+pdfstudio is not free).
+
+Key features of PDF Studio Viewer:
+
+ * Display PDFs with high fidelity
+ * Annotate & Markup PDFs
+ * Fill & Save Forms
+ * Render Digital Signatures & Layers
+ * Advanced User Interface
+ * Advanced Print & Search Options
+ * Document Storage Integrations
+ * DocuSign Integration
+
+By default PDF Studio Viewer uses the system-wide Java.
+
+If you pass OWNJAVA=yes to the SlackBuild script:
+OWNJAVA=yes ./pdfstudioviewer.SlackBuild
+a version of Java that comes packaged with PDF Studio Viewer will be
+installed under the PDF Studio Viewer installation directory, this Java
+will not be used by other programs.
+
+NOTE: The license of the sources don't permit free distribution, so
+sources must be coming from upstream project.

+# 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 ':' except on otherwise blank lines.
