+# gcc-8
+
+OpenBSD includes `gcc` in the base install. However, it includes `gcc-4.2.1`.
+If you prefer to use `gcc-8.3.0`, the names of the binaries differ so as to not
+conflict with `gcc` in base.
+
+* `egcc` - gcc
+* `eg++` - g++
+* `egdb` - gdb
+* `egfortran` - g95 / gfortran
+
+The exception being `gnat`.
