# Shell helpers for estampa. Source this from your shell rc:

# export ESTAMPA_HOST=estampa@paste.example.com
# . /path/to/extras/estampa.sh
#
# Optional:
# export ESTAMPA_URL=https://paste.example.com
# Defaults to "https://" + the host part of $ESTAMPA_HOST.
#
# Functions:
# estampaup ./file.txt upload a file, print the URL.
# estampaste file.txt upload the clipboard as <file.txt>, print the URL.
#
# estampaste uses wl-paste on Wayland and pbpaste on macOS.
