EDIT 2: golfed 1 byte from decompression script thanks to @nununoisy

bash + zpaq 1.10, 17 + 7360 = 7377 bytes

Requires the binary file g of 7360 bytes created with this compression command:

```

bash + zpaq 1.10, 17 + 1 + 7360 = <sup>7377</sup> 7378 bytes

Requires the binary file g of 7360 bytes created with this compression command: (plus one more byte for the filename g length)

EDIT: now including 1 byte for filename length

bash + zpaq, 17 + 7360 = 7377 bytes

bash + zpaq 1.10, 17 + 7360 = 7377 bytes

Note: this was done with version 1.10 of zpaq, released in 2009, obtained today for Ubuntu 18.04 via apt-get. The latest release 7.15 of zpaq not only has much more verbose option syntax, but does not even support the older options for omitting metadata. Therefore this cannot be reproduced with the current release of zpaq.
