+Description: Universal Lenient Base64 Decoder (Go library)
+ base64dec is a Universal Lenient Base64 Decoder. It's a modified version of the
+ standard base64 decoder from encoding/base64. The key differences are:
+ .
+   * Accepts both Standard and URL-safe encoding, no need to specify it
+     explicitly.
+   * Works for both padded and raw inputs.
+   * The input can be a string or a []byte, no allocation or copy is
+     performed for either.
+ .
+ The goal was to create a decoder compatible with the one used in nodejs
+ (and possibly elsewhere too). Unfortunately the standard package does
+ not expose enough API to do this efficiently, and trying all 4 possible
+ variants (standard/url, padded/raw) seemed wasteful.
