To easily check the registry for all your installations, try:

	$ ls -R /proc/reg*/HKEY*/SOFTWARE/Cygwin

to see the useful content:

	$ find /proc/reg*/HKEY*/SOFTWARE/Cygwin -type f | xargs head; echo

to get the settings from /etc/setup/setup.rc for: last-cache, last-mirror,
last-action, net-method (Direct or proxy):

	$ sed "0,/^$SETTING/d;s/^\s\+//;q" /etc/setup/setup.rc

to change it, at your own risk, type carefully:

	$ sed -i "/$SETTING/{n;s/^\s\+.*/\t$NEW/}" /etc/setup/setup.rc

I picked this up while forking apt-cyg at:
	https://github.com/BrianInglis/apt-cyg
with three pull requests against the original at:
	https://github.com/transcode-open/apt-cyg
to:
* fix postinstall processing so it works the same as current setup,
   does not rename permanent and dash scripts, and runs only once
   after all packages have been installed (even recursively);
* add apt-get-like source command with options for --download-only
   and --compile, which uses whichever is available in the package:
   -cygport script, so it can auto-pre-install build dependencies to build;
   - configure script;
   - Makefile;
   both of the latter require build dependencies manually preinstalled;
* quieten wget by adding the -nv --non-verbose option.
Download latest branch wget-non-verbose and try it if you use apt or want to
easily download and/or build sources, especially those using cygport (many):
master branch reflects the original whose author seems unresponsive lately,
so pull requests may never be merged.
