  OptControl.jl(OptControl) implements that modeling optimal control problems
with symbolic algebra system based on Julia language, and generates the
corresponding numerical optimization codes to solve them with packages from
Julia. OptControl does not define a data type, but generates a solution script
by handling Julia strings and runs the script automatically. It also provides
an interface to save script files. Meanwhile, OptControl supports
component-based modeling, which makes it easy to build the optimal control
problem of complex systems. All of OptControl's dependency packages come from
ecosystem of Julia.
