# This script lists user defined search engines in Chromium.
# It replaces {inputEncoding}, which appears in some search engine definitions, with
# UTF-8, {google:baseURL} with the Google URL, and omits other such tokens.

# can take browser name as first argument. 
# 'Google Chrome', Chromium, BraveSoftware/Brave-Browser
