+Template: metche/email
+Type: string
+Default: root
+Description: Email address to which the reports will be sent.
+ By default, metche is run periodically by a cron job which returns
+ reports containing changes made to:
+  - the changelog files,
+  - the watched files,
+  - the list of installed debian packages.
+ This option indicates to which email address those reports will be
+ sent and typically corresponds to your collective mailing-list
+ address.
+ .
+ See https://poivron.org/dev/metche/ for an example.
+ .
+ Note: metche is also able to use GnuPG to encrypt the email it sends,
+ but does not by default. See the man page and the configuration file
+ for more details.
+
+Template: metche/changelog/type
+Type: select
+Choices: Single changelog file, Multiple changelog files
+Description: Changelog monitoring type.
+ Metche monitors changelog files written by *you* and which should
+ comment the changes you made to the system. You can choose between
+ two different types of monitoring:
+  - Single changelog file monitoring or
+  - Multiple changelogs file monitoring, in which each "Changelog"
+    file in a sub-directory of a given directory will be monitored.
+
+Template: metche/changelog/file
+Type: string
+Description: Changelog file to be monitored.
+ This option sets the path of the changelog file to be monitored.
+
+Template: metche/changelog/directory
+Type: string
+Description: Changelog directory to be monitored.
+ This option sets the path of the changelog directory. Each
+ "Changelog" file should be in a sub-directory of this directory.
