/** \ingroup python
* \name Class: Rpmte
* \class Rpmte
* \brief An python rpm.te object represents an element of a transaction set.
*
* Elements of a transaction set are accessible after being added. Each
* element carries descriptive information about the added element as well
* as a file info set and dependency sets for each of the 4 types of dependency.
*
* The rpmte class contains the following methods:
*
* - te.Type() Return transaction element type (TR_ADDED|TR_REMOVED).
* - te.N() Return package name.
* - te.E() Return package epoch.
* - te.V() Return package version.
* - te.R() Return package release.
* - te.A() Return package architecture.
* - te.O() Return package operating system.
* - te.NEVR() Return package name-version-release.
* - te.Color() Return package color bits.
* - te.PkgFileSize() Return no. of bytes in package file (approx).
* - te.Depth() Return the level in the dependency tree (after ordering).
* - te.Npreds() Return the number of package prerequisites (after ordering).
* - te.Degree() Return the parent's degree + 1.
* - te.Parent() Return the parent element index.
* - te.Tree() Return the root dependency tree index.
* - te.AddedKey() Return the added package index (TR_ADDED).
* - te.DependsOnKey() Return the package index for the added package (TR_REMOVED).
* - te.DBOffset() Return the Packages database instance number (TR_REMOVED)
* - te.Key() Return the associated opaque key, i.e. 2nd arg ts.addInstall().
* - te.DS(tag) Return package dependency set.
* @param tag 'Providename', 'Requirename', 'Obsoletename', 'Conflictname'
* - te.FI(tag) Return package file info set.
* @param tag 'Basenames'
