NAME

       Alien::Package::Slp - an object that represents a slp package

DESCRIPTION

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

CLASS DATA

       The following data is global to the class, and is used to describe the slp package format, which this class processes directly.

       footer_size
	   Complete sizeof(slpformat) from slp.h in the stampede package manager source.

       footer_packstring
	   This is the pack format string for the footer. (A=space terminated character, I=unsigned integer.)

       footer_version
	   What package format are we up to now? (Lowest one this is still compatable with.)

       archtrans
	   This is a translation table between architectures and the number that represents them in a slp package.

       fieldlist
	   This is a list of all the fields in the order they appear in the footer.

FIELDS

       compresstype
	   Holds the compression type used in the slp file.

       slpkgversion
	   Holds the slp package format version of the slp file.

METHODS

       checkfile
	   Detect slp files by their extention.

       install
	   Install a slp. Pass in the filename of the slp to install.

       getfooter
	   Pulls the footer out of the slp file and returns it.

       scan
	   Implement the scan method to read a slp file.

       unpack
	   Unpack a slp file. They can be compressed in various ways, depending on what is in the compresstype field.

       build
	   Build a slp.

       conffiles
	   Set/get conffiles.

	   When the conffiles are set, the format used by slp (a colon-delimited list) is turned into the real list that is used internally. The
	   list is changed back into slp's internal format when it is retreived.

       copyright
	   Set/get copyright.

	   When the copyright is set, the number used by slp is changed into a textual description. This is changed back into a number when the
	   value is retreived.

       arch
	   Set/get arch.

	   When the arch is set, the number used by slp is changed into a textual description. This is changed back into a number when the value
	   is retreived.

       release
	   Set/get release version.

	   When the release version is retreived, it is converted to an unsigned integer, as is required by the slp package format.

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.
