+singer-analyze-record-fields
+----------
+To get an idea of how many total fields a stream of records has, you can use `singer-analyze-record-fields` to count the unique paths. This tool will count the total number of unique paths observed in a set of records, and recusively count the number of unique nested paths with a depth = 3  
+
+Currently this only works for a single stream, but it can eventually be
+extended to support multiple streams
+
+To use `singer-analyze-record-fields`, first run the tap and redirect the output to a file:
+```
+$ <tap-foo> --config <config_file> --properties <catalog_file> --catalog <catalog_file> --state <state_file> > records.txt
+```
+
+Then run `singer-analyze-record-fields` with the file as input
+```
+$ singer-analyze-record-fields < records.txt
+```
+#### A good run:
+```
+$ singer-analyze-record-fields < records.txt
