%description
The Open Ephys GUI is designed to provide a fast and flexible interface for
acquiring and visualizing data from extracellular electrodes. It features a
modular plugin architecture for processing data and interfacing with
acquisition hardware (Neuropixels, Open Ephys Acquisition Board, etc.).

Supports headless operation via --headless flag with HTTP REST API control
on port 37497.

# Open Ephys has NO install() targets — manual installation required.

# so we install everything under /usr/libexec/open-ephys/ and symlink
# /usr/bin/open-ephys to it.
