+# human-readable gtfs realtime feeds
+
+a tool to answer to the question "how to check that the gtfs realtime feed says
+what it's supposed to if for some unfortunate reason you can't read binary?".
+
+At 188 crates, it might be suspected that it gives a *slightly* over-engineered
+answer.
+
+~~~
+Usage: showrt [OPTIONS] <URL>
+
+Arguments:
+  <URL>  uri of the GTFS RT feed to fetch & display
+
+Options:
+      --json             emit the feed as json
+  -i, --ignore-nonfatal  ignore things that look wrong as long as possible
+      --no-colors        don't do terminal colours
+  -h, --help             Print help information
+  -V, --version          Print version information
+~~~
+
+### Features:
+ - fetch feeds from some url
+ - display feeds in protobuf pseudo-format, optionally with fancy colours
+ - dump the entire feed as json to process it with `jq` & friends
+ - error messages with entirely too many arrows in them
+
+### Still Todo:
+ - open local files (why do people even have these?)
+ - play nice with (input-)pipes
+ - optionally convert all dates into something more human-friendly than seconds
+   since the unix epoch
+ - optionally collapse translations that contain only one language in the output
