# 20200424 bkw: This used to be a one-line script:
# cat "${1:--}" | nc termbin.com 9999
# ...but I really wanted the "copy link to X clipboard" feature.

termbin v$VERSION

Usage: $SELF <filename> [<filename> ...]

Uses nc (netcat) to paste stdin to termbin.com, or pastes one or more
files if <filename(s)> are given. Spits out paste URL on stdout. Also
copies URL to the X clipboard if X is running and either xsel or xclip
is installed.

Only one paste is created. If you give multiple filenames, they are
concatenated together.
