+Dh_Lib is the library used by all debhelper programs to parse their
arguments and set some useful variables. It's not mandatory that your
program use Dh_Lib.pm, but it will make it a lot easier to keep it in sync
with the rest of debhelper if it does, so this is highly encouraged.
-(There used to be a version of Dh_lib.pm that was a library of functions for
-shell scripts. If you want to write a debhelper command that is a shell
-script, I can dig up that old library for you. Only the perl one is
-supported now, though.)

The init() function causes Dh_lib to parse the command line and do some other
initialization tasks.
inhibit_log()
Prevent logging the program's successful finish to
debian/*debhelper.log
+load_log($package, $hashref)
+ Loads the log file for the given package and returns a list of
+ logged commands.
+ (Passing a hashref also causes it to populate the hash.)
+write_log($cmd, $package ...)
+ Writes the log files for the specified package(s), adding
+ the cmd to the end.
+
+Sequence Addons
+---------------
+
+The dh(1) command has a --with <addon> parameter that ca be used to load
+a sequence addon named Debian::Debhelper::Sequence::<addon>.
+These addons can add/remove commands to the dh command sequences, by calling
+some functions from Dh_Lib:
+
+insert_before($existing_command, $new_command)
+ Insert $new_command in sequences before $existing_command
+
+insert_after($existing_command, $new_command)
+ Insert $new_command in sequences after $existing_command
+
+remove_command($existing_command)
+ Remove $existing_command from the list of commands to run.
