The panic was a little jarring, so I added a simple validator.

$ pxl
panic: open pxl: no such file or directory

goroutine 1 [running]:
panic(0x16c3e0, 0xc82007a330)
    /usr/local/Cellar/go/1.6.2/libexec/src/runtime/panic.go:481 +0x3e6
main.main()
    /Users/dcam/gopath/src/github.com/ichinaski/pxl/main.go:50 +0xb2

$ ./pxl
Usage: ./pxl <filename>

Close the image with <ESC>.
