ragel 6.10-4 (riscv64 binary) in ubuntu lunar

 Ragel compiles finite state machines from regular languages into C, C++,
 Objective-C, D, Ruby or Java code. Ragel allows the programmer to embed
 actions at any point in a regular language. Non-determinism can be
 controlled through the use of embedded priorities and guarded regular
 language operators. Ragel also supports the construction of scanners and
 the building of state machines using state-charts. Ragel can be used to
 create robust recognizers and parsers which run very fast. It can work
 with integer-sized alphabets and can compile large state machines.
 The generated code has no dependencies.
