+Type aliases for many constants.
+
+This file is generated by typenum's build script.
+
+For unsigned integers, the format is `U` followed by the number. We define aliases for
+
+- Numbers 0 through {highest}
+- Powers of 2 below `u64::MAX`
+- Powers of 10 below `u64::MAX`
+
+These alias definitions look like this:
+
+```rust
+use typenum::{{B0, B1, UInt, UTerm}};
+
+# #[allow(dead_code)]
+type U6 = UInt<UInt<UInt<UTerm, B1>, B1>, B0>;
+```
+
+For positive signed integers, the format is `P` followed by the number and for negative
+signed integers it is `N` followed by the number. For the signed integer zero, we use
+`Z0`. We define aliases for
+
+- Numbers -{highest} through {highest}
+- Powers of 2 between `i64::MIN` and `i64::MAX`
+- Powers of 10 between `i64::MIN` and `i64::MAX`
+
+These alias definitions look like this:
+
+```rust
+use typenum::{{B0, B1, UInt, UTerm, PInt, NInt}};
+
+# #[allow(dead_code)]
+type P6 = PInt<UInt<UInt<UInt<UTerm, B1>, B1>, B0>>;
+# #[allow(dead_code)]
+type N6 = NInt<UInt<UInt<UInt<UTerm, B1>, B1>, B0>>;
+```
+
+# Example
+```rust
+# #[allow(unused_imports)]
+use typenum::{{U0, U1, U2, U3, U4, U5, U6}};
+# #[allow(unused_imports)]
+use typenum::{{N3, N2, N1, Z0, P1, P2, P3}};
+# #[allow(unused_imports)]
+use typenum::{{U774, N17, N10000, P1024, P4096}};
+```
+
+We also define the aliases `False` and `True` for `B0` and `B1`, respectively.
