# Builds the native gelectron binary and installs it plus the JS compat
# layer so `gelectron <app>` works from anywhere.
#
# Install layout (binary looks up compat/ next to itself):
#   <PREFIX>/gelectron          native binary
#   <PREFIX>/compat/*.js        Electron API compat layer
#
# Usage:
#   ./scripts/install.sh                install to ~/.local/bin
#   PREFIX=~/bin ./scripts/install.sh   install elsewhere
#   ./scripts/install.sh --uninstall    remove the installed files
