# Tool to send and receive files using Tox NGC FileTransfers
currently on prototype FT1

## Example

### sender (seeder)
`$ tox_ngc_ft1_tool -F sender.tox -G <ngc_chat_id> -a sha1_info -f file_to_transfer`

this will print this tools tox_id and the generated info_hash

### receivers (leechers)
`$ tox_ngc_ft1_tool -F sender.tox -G <ngc_chat_id> -a sha1_info -D <info_hash>`

this will first download the info using the info_hash and then all the file chunks listed in the info
while simultaneously resharing allready downloaded chunks and info (swarming)
to increase the amount of parallel chunk down/up loads, you can increase the value with the -I and -O option. the default for -I is 32 and for -O 16, which are relatively low numbers, which in practice can get you up to ~700KiB/s.

## Usage

```
$ tox_ngc_ft1_tool
~~~ HELP ~~~
 meta:
 -v version info
