+# A very simple Nim package scanner.
+#
+# Scan the package list from:
+# https://github.com/nim-lang/packages/blob/master/packages.json
+#
+# Check the packages for:
+#  * Missing/unknown license
+#  * Missing description
+#  * Missing name
+#  * Missing/unknown method
+#  * Missing/unreachable repository
+#
+# Usage: nim c -d:ssl -r package_scanner.nim
