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.
