# Read README.md, ipcalc (it's a Perl script), and 'man ./ipcalc.1'
# If upgrading, read changelog

# Become root to install it
su

install -m 0755 ipcalc /usr/local/bin/
install -m 0755 ipcalc.1 /usr/local/man/man1/

# If you also want to use it as a CGI script, see the example use at
# https://jodies.de/ipcalc/
# and look at ipcalc.cgi, which is the file that makes that web page,
# and ipcalc.gif and ipcalculator.png
#
# If using source-installed Apache HTTP 2.x, you might put them in
# /usr/local/apache2/cgi-bin and make them owned by root:daemon with
# 0750 permissions or something like that... Or set up ScriptAlias
# somewhere else...

exit

# Save the source for later
cd
