### 4.3 Run-time Module Loading

With our built module, we can now load it into `hacchpsim`. One way is to pass libraries on the command line using the `-l` option and the `-L` option.

         $ hacchpsim -lbar chptest.haco-a
         loaded function: `alert_me'
         loaded function: `twiddle'
         chpsim> watchall-events
         chpsim> step 40

The alternative is to add library paths and load libraries after the simulator is launched.

         $ hacchpsim chptest.haco-a
         chpsim> dlopen bar
         loaded function: `alert_me'
         loaded function: `twiddle'
         chpsim> watchall-events
         chpsim> step 40

Loading libraries on the command-line and in the interpreter is allowed, and works as expected. `chpsim` can load arbitrarily many libraries (within the limits of the operating system), and as long as the registered function names don't conflict.
