NAME

       Alien::Package::Deb - an object that represents a deb package

DESCRIPTION

       This is an object class that represents a deb package. It is derived from Alien::Package.

FIELDS

       have_dpkg_deb
	   Set to a true value if dpkg-deb is available.

       dirtrans
	   After the build stage, set to a hash reference of the directories we moved files from and to, so these moves can be reverted in the
	   cleantree stage.

       fixperms
	   If this is set to true, the generated debian/rules will run dh_fixperms.

METHODS

       init
	   Sets have_dpkg_deb if dpkg-deb is in the path. I prefer to use dpkg-deb, if it is available since it is a lot more future-proof.

       checkfile
	   Detect deb files by their extention.

       install
	   Install a deb with dpkg. Pass in the filename of the deb to install.

       test
	   Test a deb with lintian. Pass in the filename of the deb to test.

       getcontrolfile
	   Helper method. Pass it the name of a control file, and it will pull it out of the deb and return it.

       scan
	   Implement the scan method to read a deb file.

       unpack
	   Implement the unpack method to unpack a deb file.

       getpatch
	   This method tries to find a patch file to use in the prep stage. If it finds one, it returns it. Pass in a list of directories to
	   search for patches in.

       prep
	   Adds a populated debian directory the unpacked package tree, making it ready for building. This can either be done automatically, or
	   via a patch file.

       build
	   Build a deb.

       cleantree
	   Delete the entire debian/ directory.

       package
	   Set/get package name.

	   Always returns the packge name in lowercase with all invalid characters rmoved. The name is however, stored unchanged.

       version
	   Set/get package version.

	   When the version is set, it will be stripped of any epoch. If there is a release, the release will be stripped away and used to set the
	   release field as a side effect. Otherwise, the release will be set to 1.

	   More sanitization of the version is done when the field is retrieved, to make sure it is a valid debian version field.

       release
	   Set/get package release.

	   Always returns a sanitized release version. The release is however, stored unchanged.

       description
	   Set/get description

	   Although the description is stored internally unchanged, this will always return a sanitized form of it that is compliant with Debian
	   standards.

       date
	   Returns the date, in rfc822 format.

       email
	   Returns an email address for the current user.

       username
	   Returns the user name of the real uid.

       postinst
	   Returns the postinst. This may include generated shell code to set owners and groups from the owninfo field, and update modes from the
	   modeinfo field.

NAME

       Alien::Package::Rpm - an object that represents a rpm package

DESCRIPTION

       This is an object class that represents a rpm package. It is derived from Alien::Package.

FIELDS

       prefixes
	   Relocatable rpm packages have a prefixes field.

METHODS

       checkfile
	   Detect rpm files by their extention.

       install
	   Install a rpm. If RPMINSTALLOPT is set in the environement, the options in it are passed to rpm on its command line.

       scan
	   Implement the scan method to read a rpm file.

       unpack
	   Implement the unpack method to unpack a rpm file. This is a little nasty because it has to handle relocatable rpms and has to do a bit
	   of permissions fixing as well.

       prep
	   Prepare for package building by generating the spec file.

       cleantree
	   Delete the spec file.

       build
	   Build a rpm. If RPMBUILDOPT is set in the environement, the options in it are passed to rpm on its command line.

	   An optional parameter, if passed, can be used to specify the program to use to build the rpm. It defaults to rpmbuild.

       version
	   Set/get version.

	   When retreiving the version, remove any dashes in it.

       postinst
       postrm
       preinst
       prerm
	   Set/get script fields.

	   When retrieving a value, we have to do some truely sick mangling. Since debian/slackware scripts can be anything -- perl programs or
	   binary files -- and rpm is limited to only shell scripts, we need to encode the files and add a scrap of shell script to make it
	   unextract and run on the fly.

	   When setting a value, we do some mangling too. Rpm maintainer scripts are typically shell scripts, but often lack the leading shebang
	   line.  This can confuse dpkg, so add the shebang if it looks like there is no shebang magic already in place.

	   Additionally, it's not uncommon for rpm maintainer scripts to contain bashisms, which can be triggered when they are ran on systems
	   where /bin/sh is not bash. To work around this, the shebang line of the scripts is changed to use bash.

	   Also, if the rpm is relocatable, the script could refer to RPM_INSTALL_PREFIX, which is set by rpm at run time. Deal with this by
	   adding code to the script to set RPM_INSTALL_PREFIX.

       arch
	   Set/get arch field. When the arch field is set, some sanitizing is done first to convert it to the debian format used internally. When
	   it's retreived it's converted back to rpm form from the internal form.
