Subject: Two new utilities written in Go.
X-Git-Url: https://de.git.xonotic.org/?p=xonotic%2Fxonstat.git;a=commitdiff_plain;h=9a2bd083a5df36a119e99c397e603d4f6610f575

Two new utilities written in Go.

xs_parselog parses XonStat log and extracts/recreates requests
into text files, one request per file.

xs_submit takes a XonStat request via a text file and submits it
to a user-specified URL.

Both of these utlities can be run with "go run <filename> [opts]"
after having install the Go programming language on your machine.
Alternatively, one can build executables with "go build <filename>".
