# DESCRIPTION: Run the Brave browser to view completed notes

# BUGS: 2020-06-01: New version of Brave (now called 'brave-browser')
|
|
# necessitates changes in how this script was originally
|
|
# designed. The softlink between hpr????.out and hpr????.html
|
|
# has been converted to a hard link.
|
|
# NOTES: We use a link 'do_browser' to point to whichever script runs
|
|
# the preferred browser. It's been Brave for several years now,
|
|
# but we haven't changed this!
|
|
# 2022-12-22: We now write state changes to the file .status in
|
|
# the show directory, so we need to do that here too. Also
|
|
# changed to using the function library for cleanup_temp.
