clipmenu is a simple clipboard manager using dmenu and xsel. Launch this
when you want to select a clip.

All arguments are passed through to dmenu itself.

Environment variables:

- $CM_DIR: specify the base directory to store the cache dir in (default: $XDG_RUNTIME_DIR, $TMPDIR, or /tmp)
- $CM_HISTLENGTH: specify the number of lines to show in dmenu/rofi (default: 8)
- $CM_LAUNCHER: specify a dmenu-compatible launcher (default: dmenu)
- $CM_OUTPUT_CLIP: if set, output clip selection to stdout
