+      primecount is a command-line program and C/C++ library that counts the
+      primes below an integer x ≤ 10^31 using highly optimized implementations
+      of the combinatorial prime counting algorithms.
+
+      primecount includes implementations of all important combinatorial prime
+      counting algorithms known up to this date all of which have been
+      parallelized using OpenMP. primecount contains the first ever open source
+      implementations of the Deleglise-Rivat algorithm and Xavier Gourdon's
+      algorithm (that works). primecount also features a novel load balancer
+      that is shared amongst all implementations and that scales up to hundreds
+      of CPU cores. primecount has already been used to compute several prime
+      counting function world records.
