 Originally developed in support of the [PyGPSClient](https://github.com/semuconsulting/PyGPSClient) GUI GNSS application, the utilities provided by pygnssutils can also be used in their own right:
 
-1. `GNSSReader` class. This is essentially an amalgamation of the `*Reader` classes in all the subsidiary parsers listed above, allowing the user to seamlessly stream any of NMEA, UBX, SBF, UNI, QGC, RTCM3 and SPARTN message protocols concurrently from a single stream.

 1. `GNSSStreamer` class and its associated [`gnssstreamer`](#gnssstreamer) (*formerly `gnssdump`*) CLI utility. This is essentially a configurable bidirectional input/output wrapper around the `GNSSReader` class with flexible message formatting, filtering and output handling options for NMEA, UBX, SBF, UNI, QGC and RTCM3 protocols.
 1. `GNSSSocketServer` class and its associated [`gnssserver`](#gnssserver) CLI utility. This implements a TCP Socket Server for GNSS data streams which is also capable of being run as a simple NTRIP Server/Caster.
 1. `GNSSNTRIPClient` class and its associated [`gnssntripclient`](#gnssntripclient) CLI utility. This implements
 a simple NTRIP Client which receives RTCM3 or SPARTN correction data from an NTRIP Server and (optionally) sends this to a
 designated output stream.

 1. `SocketServer` class based on the native Python `ThreadingTCPServer`. Capable of operating in two modes - Socket Server or NTRIP Caster. Provides two alternate client request handler classes - `ClientHandler` (HTTP) or `ClientHandlerTLS` (HTTPS).
-1. `RinexConverter` class and its associated [`pyrinexconv`](#rinexconvert) CLI utility. This implements a binary GNSS data log file to RINEX text file conversion facility. **NB: RINEX conversion is currently an experimental work in progress (*contributions and feedback welcome*)**

-class pygnssutils.gnssmqttclient.GNSSMQTTClient(app=None, **kwargs)
-```
-
-The `GNSSMQTTClient` class provides a basic SPARTN IP (MQTT) Client capability and forms the basis of a [`gnssmqttclient`](#gnssmqttclient) CLI utility. It receives RTK correction data from a SPARTN IP (MQTT) location service (e.g. the u-blox / Thingstream PointPerfect service) and (optionally) sends this to a designated output stream.
-
-### CLI Usage:
-
-The `clientid` provided by the location service may be set as environment variable `MQTTCLIENTID`. If this environment variable is set and the TLS certificate (\*.crt) and key (\*.pem) files provided by the location service are placed in the user's `HOME` directory, the utility can use these as default settings and may be invoked without any arguments.
-
-Assuming the Python 3 scripts (bin) directory is in your PATH, the CLI utility may be invoked from the shell thus (press CTRL-C to terminate):
-
-```shell
-gnssmqttclient --clientid yourclientid --server pp.services.u-blox.com --port 8883 --region eu --mode 0 --topic_ip 1 --topic_mga 1 --topic_key 1 --tlscrt '/Users/{your-user}/device-{your-clientid}-pp-cert.crt' --tlskey '/Users/{your-user}/device-{your-client-id}-pp-key.pem'} --spartndecode 0 --clioutput 0 --verbosity 2
-```

-...
-```
-
-Command line arguments can be stored in a configuration file and invoked using the `-C` or `--config` argument. The location of the configuration file can be set in environment variable `GNSSMQTTCLIENT_CONF`.
-
-For help and full list of optional arguments, type:
-
-```shell
-gnssmqttclient -h
-```
-
-Refer to the [pyspartn documentation](https://github.com/semuconsulting/pyspartn?tab=readme-ov-file#reading) for further details on decrypting encrypted (`eaf=1`) SPARTN payloads.

 ### RELEASE 1.2.6
 
 1. Add `msgfilter` argument to GNSSReader - will only parse GNSS messages where msgid is in msgfilter. msgid is string type for NMEA, otherwise integer.
