+### pfile ###
+
+Wrapper around *file* utility that reads STDIN, stores it in a temporary file
+(using Python's *tmpfile.mkstemp*),calls the utility on it and returns output
+(and of course, deletes the tmpfile afterwards).
+
+This is useful in cases like when debugging a HTTP server with utility like
+*curl*, and when we don't want to see the actual output, yet still want to know
+what it looks like.  Using pfile on pipe, we can easily combine the power
+of *file* with the simplicity of *curl*:
+
+
