programs in debhelper use pairs of files and destinations or slightly more
complicated formats.
-Note that if a package is the first (or only) binary package listed in
-F<debian/control>, debhelper will use F<debian/foo> if no F<debian/package.foo>

+Note for the first (or only) binary package listed in
+F<debian/control>, debhelper will use F<debian/foo> when there's no

In some rare cases, you may want to have different versions of these files
for different architectures or OSes. If files named debian/I<package>.foo.I<ARCH>
"B<dpkg-architecture -qDEB_HOST_ARCH_OS>",
then they will be used in preference to other, more general files.

+Mostly, these config files are used to specify lists of various types of
files. Documentation or example files to install, files to move, and so on.
When appropriate, in cases like these, you can use standard shell wildcard
characters (B<?> and B<*> and B<[>I<..>B<]> character classes) in the files.
-
You can also put comments in these files; lines beginning with B<#> are
ignored.
+The syntax of these files is intentionally kept very simple to make them
+easy to read, understand, and modify. If you prefer power and complexity,
+you can make the file executable, and write a program that outputs
+whatever content is appropriate for a given situation. When you do so,
+the output is not further processed to expand wildcards or strip comments.

=head1 SHARED DEBHELPER OPTIONS
The following command line options are supported by all debhelper programs.

-=head1 COMPATABILITY LEVELS
+=head1 COMPATIBILITY LEVELS
From time to time, major non-backwards-compatible changes need to be made
to debhelper, to keep it clean and well-designed as needs change and its
it modifies its behavior in various ways.
Tell debhelper what compatibility level to use by writing a number to
-F<debian/compat>. For example, to turn on v8 mode:
+F<debian/compat>. For example, to turn on v9 mode:
+
+ % echo 9 > debian/compat
+
+Your package will also need a versioned build dependency on a version of
+debhelper equal to (or greater than) the compatibility level your package
+uses. So for compatibility level 9, ensure debian/control has:
- % echo 8 > debian/compat
+ Build-Depends: debhelper (>= 9)
Unless otherwise indicated, all debhelper documentation assumes that you
are using the most recent compatibility level, and in most cases does not

Debhelper includes support for udebs. To create a udeb with debhelper,
-add "B<Package-Type: udeb>" to the package's stanza in F<debian/control>, and
-build-depend on debhelper (>= 4.2). Debhelper will try to create udebs that

-=head2 Build depends
-
-Once your package uses debhelper to build, be sure to add
-debhelper to your Build-Depends line in F<debian/control>. You should
-build-depend on a version of debhelper equal to (or greater than) the
-debhelper compatibility level your package uses. So if your package used
-compatibility level 7:
-
- Build-Depends: debhelper (>= 7)
