+w_scan2 is a small channel scan tool which generates
+ATSC, DVB-C, DVB-S/S2 and DVB-T/T2 channels.conf files.
+
+It's based on the old "scan" tool from linuxtv-dvb-apps-1.1.0
+
+The differences are:
+- no initial tuning data needed, because scanning without this data is
+  exactly what a scan tool like this should do
+- it detects automatically which DVB/ATSC card to use
+- much more output formats, interfacing to other dtv software.
+
+w_scan2 is a fork of the original w_scan
+from https://www.gen2vdr.de/wirbel/w_scan/index2.html
+
+main changes from w_scan to w_scan2
+- keep duplicate transponders by default because a stronger transponder
+  with the same ID might have a higher frequency and be discarded
+  simply because it's scanned later.
+- Also don't replace the current transponder with an advertised one by
+  default. The latter may have a lower signal strength.
+  https://stefantalpalaru.wordpress.com/2016/02/04/scan-all-the-things/
+- The old behaviour can be enabled with -d
+  (--delete-duplicate-transponders).
+- re-enable VHF band III in Europe

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
