How to use

ecs command is a compiler that will translate ECS to CovScript 3, but can use like an 'interpreter' (will compile your code before run automatically)

Usage:
    ecs [options...] <FILE> [arguments...]
    ecs [options...]

Interpreter Options:
   -f            Disable compile cache
   -m            Disable beautify
   -c            Check grammar only
   -g            Generate cSYM info
   -d            Run debugger
   -o <PATH>     Set output path
   -- <ARGS>     Pass parameters to CovScript

Interpreter REPL Options:
   -s            Close the command prompt
   -r <ARGS...>  Set arguments for REPL

Common Options:
    Option       Function
   -h            Show help information
   -v            Show version infomation
   -u <CHARSET>  Set unicode charset

Compatibility Notice

1. The program translated by ECS Compiler will depends on package ecs.
2. The behavior of Lambda Expression will be very different.
3. Separated exception system. Please call e = ecs.handle_exception(e) to solve compatible problem in CovScript 3 when catch exception from ECS Packages.
4. To support new and gcnew operator with arguments, please define construct function separately.
