ectors of polynomials <tt>vec_ZZ_pX</tt>,
<tt>vec_ZZX</tt>, etc.

<p>
There are also a number of generic pair classes defined,
not explicitly documented elsewhere:

<ul>
<li> <tt>pair_GF2EX_long</tt>
<li> <tt>pair_GF2X_long</tt>
<li> <tt>pair_ZZX_long</tt>
<li> <tt>pair_ZZ_pEX_long</tt>
<li> <tt>pair_ZZ_pX_long</tt>
<li> <tt>pair_lzz_pEX_long</tt>
<li> <tt>pair_lzz_pX_long</tt>
</ul>

These decalarations are found in "<tt>.h</tt>" files with
corresponding names.
