debian/control. Also, debhelper commands should accept the same sort of
information that appears in the config files, on their command lines, if
possible, and apply that information to the first package they act on.
+The config file format should be as simple as possible, generally just a
+list of files to act on.
Debhelper programs should never modify the debian/postinst, debian/prerm,
etc scripts. Instead, they can add lines to debian/postinst.debhelper, etc.
In general, files named debian/*.debhelper are internal to debhelper, and
their existence or use should not be relied on by external programs such as
-the build process of a package.
+the build process of a package. These files will be deleted by dh_clean.
Debhelper programs should default to doing exactly what policy says to do.
-a, and -p. To help you make this work right, Dh_Lib.pm handles argument
processing. Just call init().
+You can add support for additional options to your command by passing an
+options hash to init(). The hash is then passed on the Getopt::Long to
+parse the command line options. For example, to add a --foo option, which
+sets $dh{FOO}:
+
+init(options => { foo => \$dh{FOO} });
+
After argument processing, some global variables are used to hold the
results; programs can use them later. These variables are elements of the
%dh hash.
packages
-n NOSCRIPTS if set, do not make any modifications to the
package's postinst, postrm, etc scripts.
+-o ONLYSCRIPTS if set, only make modifications to the
+ package's scripts, but don't look for or
+ install associated files.
-X EXCLUDE exclude a something from processing (you
decide what this means for your program)
(This is an array)
- EXCLUDE_FIND same as DH_EXCLUDE, except all items are put
+-X EXCLUDE_FIND same as EXCLUDE, except all items are put
into a string in a way that they will make
find find them. (Use ! in front to negate
- that, of course)
--x INCLUDE_CONFFILES
- include conffiles. It's -x for obscure
- historical reasons.
+ that, of course) Note that this should
+ only be used inside complex_doit(), not in
+ doit().
-d D_FLAG you decide what this means to your program
--r R_FLAG you decide what this means to your program
--k K_FLAG you decide what this means to your program
+-k K_FLAG used to turn on keeping of something
-P TMPDIR package build directory (implies only one
package is being acted on)
-u U_PARAMS will be set to a string, that is typically
parameters your program passes on to some
other program. (This is an array)
--m M_PARAMS will be set to a string, you decide what it
- means to your program
--l L_PARAMS will be set to a string, you decide what it
- means to your program
-V V_FLAG will be set to a string, you decide what it
means to your program
-V V_FLAG_SET will be 1 if -V was specified, even if no
those processed here), will apply to all
binary packages the program acts on, not just
the first
---init-script INIT_SCRIPT will be set to a string, which specifies an
- init script name (probably only
- dh_installinit will ever use this)
---sourcedir SOURCEDIR will be set to a string (probably only
- dh_movefiles will ever use this)
---destdir DESTDIR will be set to a string (probably only
- dh_builddeb will ever use this)
---filename FILENAME will be set to a string
---flavor FLAVOR will be set to a string (probably only
- dh_installemacsen will ever use this)
---number PRIORITY will be set to a number (deprecated)
+--sourcedir SOURCEDIR will be set to a string
+--destdir DESTDIR will be set to a string
--priority PRIORITY will be set to a number
+--mainpackage MAINPACKAGE controls which package is treated as the
+ main package to act on
+--name NAME a name to use for installed files, instead of
+ the package name
+--error-handler ERROR_HANDLER a function to call on error
Any additional command line parameters that do not start with "-" will be
ignored, and you can access them later just as you normally would.
-If you need a new command line option, just ask me, and I will add it.

Global variables:
----------------
(optional)
This command automatically adds shell script snippets to a debian
maintainer script (like the postinst or prerm).
+ Note that in v6 mode and up, the snippets are added in reverse
+ order for the removal scripts.
dirname($pathname)
Return directory part of pathname.
basename($pathname)
excludefile($filename)
This function returns true if -X has been used to ask for the file
to be excluded.
+is_udeb($package)
+ Returns true if the package is marked as a udeb in the control
+ file.
+udeb_filename($package)
+ Returns the filename of the udeb package.
+getpackages($type)
+ Returns a list of packages in the control file.
+ Must pass "arch" or "indep" or "same" to specify arch-dependent or
+ -independent or same arch packages. If nothing is specified, returns all
+ packages.
+ As a side effect, populates %package_arches and %package_types with
+ the types of all packages (not only those returned).
+inhibit_log()
+ Prevent logging the program's successful finish to
+ debian/*debhelper.log
