.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Back-end for \f(CW\*(C`dh_components\*(C'\fR command. The module has three tasks:
.IP "merging of documents (not implemented);" 4
.IX Item "merging of documents (not implemented);"
.PD 0
.ie n .IP "merging of ""substvar"" merging (not implemented);" 4

.IX Item "cascading implementation of component build process (not implemented)."
.PD
.SH "INTERFACE"
.IX Header "INTERFACE"
.SS "new"
.IX Subsection "new"
This is a constructor which takes a number of named arguments.
.ie n .IP """dir""" 4
.el .IP "\f(CWdir\fR" 4
.IX Item "dir"
This is the path to a components directory. Typically
this will just be \f(CW\*(C`debian/components\*(C'\fR. This argument is mandatory.
.ie n .IP """package""" 4
.el .IP "\f(CWpackage\fR" 4
.IX Item "package"
This is the package name and is mandatory.
.ie n .IP """build_stages""" 4
.el .IP "\f(CWbuild_stages\fR" 4
.IX Item "build_stages"
If this argument, an array reference, is given it will override the normal
sequence of build stages.
.ie n .IP """component""" 4
.el .IP "\f(CWcomponent\fR" 4
.IX Item "component"
If this parameter, an array reference, is set only those components listed will
be considered.
.ie n .IP """rules_locations""" 4
.el .IP "\f(CWrules_locations\fR" 4
.IX Item "rules_locations"
If this parameter, an array reference, is given it will override the normal
location of build stage scripts.
.SS "build_stages"
.IX Subsection "build_stages"
This returns the build stages in the order in which they should occur:
copy, patch, config, build, test, install.
.SS "directory"
.IX Subsection "directory"
This returns the directory name that was passed to the constructor.
.SS "package"
.IX Subsection "package"
This returns the package name that was passed to the constructor.
.SS "components"
.IX Subsection "components"
This returns an array listing the components found in that component directory.
.SS "script"
.IX Subsection "script"
This method takes two arguments, the component and the build stage, and returns
the script that needs to be run.
.SS "build_copyright"
.IX Subsection "build_copyright"
If this method finds a file \f(CW\*(C`copyright.in\*(C'\fR in the components directory, it
merges in any component copyright files in the component directories and
writes the result to the specified location.
.SS "substvars"
.IX Subsection "substvars"
This method returns the appropriate \f(CW\*(C`substvar\*(C'\fR variables parsed from
\&\f(CW\*(C`control\*(C'\fR files in each component sub-directory as a hash reference.
.SH "CONFIGURATION AND ENVIRONMENT"
.IX Header "CONFIGURATION AND ENVIRONMENT"
Debian::Debhelper::Dh_components requires no configuration files or environment variables.
.SH "DEPENDENCIES"
.IX Header "DEPENDENCIES"
None.
.SH "BUGS AND LIMITATIONS"
.IX Header "BUGS AND LIMITATIONS"
This module is only really intended for Debian and related systems.
