$ cat ATTIC/mathml-demo.ms
.LP

.DS C
.EQ
a times b inf c partial d == e != f +- g -> h <- i << j >> k grad
l del m cdot n cdots o approx p

OMICRON PHI PI PSI RHO SIGMA TAU UPSILON XI ZETA
alpha beta chi delta epsilon eta gamma iota kappa lambda mu nu omega
omicron phi pi psi rho sigma tau upsilon xi zeta
