build up a crystal structure L1_0(AuCu)

Dear all,
I want to build up a crystal structure like L1_0(AuCu), and I don’t know how to
set these 14 atoms in an input file or a data file?
The crystal structure parameters of L1_0(AuCu) are as follows.
14 atoms
AuCu & P4/mmm (#123) & tP4 & L1_0 (carte. coord.)
Cu 0.00000000 1.98150000 1.83550000
Au 0.00000000 3.96300000 0.00000000
Cu 1.98150000 3.96300000 1.83550000
Au 0.00000000 3.96300000 3.67100000
Au 0.00000000 0.00000000 0.00000000
Cu 1.98150000 0.00000000 1.83550000
Au 0.00000000 0.00000000 3.67100000
Au 1.98150000 1.98150000 0.00000000
Cu 3.96300000 1.98150000 1.83550000
Au 1.98150000 1.98150000 3.67100000
Au 3.96300000 3.96300000 0.00000000
Au 3.96300000 3.96300000 3.67100000
Au 3.96300000 0.00000000 0.00000000
Au 3.96300000 0.00000000 3.67100000
Your reply is my greatest achievement.
Thanks.

See the lattice and create_atoms commands. You can define
basis vectors and atom coords and types
within a unit cell and then tile the simulation box with the lattice.

I guess I'm done for the day ...
