+DESCRIPTION="Ghostscript is an interpreter for the PostScript language and for PDF"
+HOMEPAGE="http://ghostscript.com/"
+
+# Maintainer notes about djvu support:
+# gsdjvu has not seen any commits since July 2016, which was also roughly the time
+# when ghostscript started rearranging internals. Issues I found so far:
+# * gs_state and gs_imager_state got unified into gs_gstate
+# * decode_glyph changed arguments and semantics (it doesnt give you the unicode now,
+# but the length of the required byte array, which you have to allocate and fill)
+# * gs_text_enum_t has lost its element pis (???)
