+%description
+SNG (Scriptable Network Graphics) is a minilanguage designed
+specifically to represent the entire contents of a PNG (Portable
+Network Graphics) file in an editable form. Thus, SNGs representing
+elaborate graphics images and ancillary chunk data can be readily
+generated or modified using only text tools.
+
+SNG is implemented by a compiler/decompiler called sng that losslessly
+translates between SNG and PNG.
