[ANN] dstm's ZCash / Equihash Nvidia Miner v0.6.1 (Linux / Windows)

[James Bond]

#################################################
# dstm's ZCash Cuda miner
#################################################

I've written it initially for my own purpose. It performs pretty well - so here it is.
Compatible with devices having Compute Capability 5.0 and greater i.e. it should run fine on Maxwell/Pascal GPUs.
Supports every server using the stratum protocol. If you have issues with certain pools pls. report them here.
Contains 2% devfee.
Suggestions are welcome.

Features:
To get help just start zm without any arguments

Code:

ZM 0.6.1, dstm's ZCASH/Equihash Cuda Miner

Usage:
zm --server hostname --port port_nr --user user_name
[--pass password] [options]...

zm --cfg-file[=path]

Stratum:
--server Stratum server hostname
prefix hostname with 'ssl://' for encrypted
connections - e.g. ssl://mypool.com
--port Stratum server port number
--user Username
--pass Worker password

Options:
--help Print this help
--list-devices List available cuda devices

--dev Space separated list of cuda devices to use.
If this option is not given all available devices
are used.

--time Enable output of timestamps
--color colorize the output

--logfile [=path] Append logs to the file named by 'path'
If 'path' is not given append to 'zm.log' in
current working directory.
--noreconnect Disable automatic reconnection on network errors.

--temp-target =dev_id:temp-target[,dev_id:temp-target] ...
In C - If set, enables temperature controller.
The workload of each GPU will be continuously
adjusted such that the temperature stays around
this value. It is recommended to set your fan speed
to a constant value when using this setting.
Example: --temp-target=0:65,2:70

--intensity =dev_id:intensity[,dev_id:intensity] ...
Reduce the load which is put on the GPU - valid
intensity range ]1.0-0.0[.
Example: --intensity=0:0.893,2:0.8

--telemetry [=ip:port]. Starts telemetry server. Telemetry data
can be accessed using a web browser(http) or by json-rpc.
If no arguments are given the server listens on
127.0.0.1:2222 - Example: --telemetry=0.0.0.0:2222
Valid port range [1025-65535]

--cfg-file [=path] Use configuration file. All additional command
line options are ignored - configuration is done only
through configuration file. If 'path' is not given
use 'zm.cfg' in current working directory.

--pool =hostname,port_nr,user_name[,pass]
Setup additional failover pools.

Example:
zm --server servername.com --port 1234 --user username
