+# jar just does a better job of extracting zip files than either
+# unzip or 7z.
+#
+# unzip does not support files that are "missing end of central directory header".
+# 
+# 7z handles most zip files, but fails on some zip archives, inexplicably seeing
+# only the *last* entry in the zip archive (though 7z thinks it succeeded). See
+# StarCam firmware CH-sys-48.53.64.67.zip.
