destiny-cli is a command line interface to the bungie-platform-destiny API
It builds on the Go API client (work in progress) available on github
Working but not feature complete. Documentation of commands and subcommands needs work.
Currently requires a working Go development setup I can release binaries if anyone cares enough to need them but is not themselves a developer (which seems unlikely as this tool just spits out gobs of JSON at you, mostly)
go get github.com/FederationOfFathers/destiny/destiny-cli
You will need a working API key for the program to be of much use
