That type can be +used to know what fields are allowed and in what order they must be +output. + +The types are constants that are exported by default. Here's the full +list: + +=over 4 + +=item CTRL_UNKNOWN + +This type is the default type, it indicates that the type of control +information is not yet known. + +=item CTRL_INFO_SRC + +Corresponds to the first block of information in a F<debian/control> file in +a Debian source package. + +=item CTRL_INFO_PKG + +Corresponds to subsequent blocks of information in a F<debian/control> file +in a Debian source package. + +=item CTRL_REPO_RELEASE + +Corresponds to a F<Release> file in a repository. + +=item CTRL_INDEX_SRC + +Corresponds to an entry in a F<Sources> file of a source package +repository. + +=item CTRL_INDEX_PKG + +Corresponds to an entry in a F<Packages> file of a binary package +repository. + +=item CTRL_PKG_SRC + +Corresponds to a .dsc file of a Debian source package. + +=item CTRL_PKG_DEB + +Corresponds to the F<control> file generated by dpkg-gencontrol +(F<DEBIAN/control>) and to the same file inside .deb packages. + +=item CTRL_FILE_BUILDINFO + +Corresponds to a .buildinfo file. + +=item CTRL_FILE_CHANGES + +Corresponds to a .changes file. + +=item CTRL_FILE_VENDOR + +Corresponds to a vendor file in $Dpkg::CONFDIR/origins/. + +=item CTRL_FILE_STATUS + +Corresponds to an entry in dpkg's F<status> file ($Dpkg::ADMINDIR/status). + +=item CTRL_CHANGELOG + +Corresponds to the output of dpkg-parsechangelog. + +=item CTRL_COPYRIGHT_HEADER + +Corresponds to the header control block in a F<debian/copyright> file in +machine readable format. + +=item CTRL_COPYRIGHT_FILES + +Corresponds to a files control block in a F<debian/copyright> file in +machine readable format. + +=item CTRL_COPYRIGHT_LICENSE + +Corresponds to a license control block in a F<debian/copyright> file in +machine readable format. + +=item CTRL_TESTS + +Corresponds to a package tests control file in F<debian/tests/control>. + +=back + +=head1 METHODS + +All the methods of Dpkg::Control::Hash are available.
