adevs_v1_compat is a backwards compatibility module for adevs-2.0.5 and up. It provides some limited backwards compatibility with adevs-1.3.x and adevs-1.4 models. See the API documentation for details. Here is the feature summary;

• Contains the adevs-1.x object class and dbl, integ, and strng classes.
• Support for the adevs_bag, adevs_set, and adevs_hashtable classes.
  
• adevs-1.x atomic models can be used as components in an adevs-2.x simulation that is built with the PortValue<unsigned long,object*> basic input/output type. Includes support for redefining the ADEVS_PORT_TYPE and ADEVS_IO_TYPE using the adevs_config.h file.
  
• Support for the staticDigraph class.
• Support for adevs-1.x DS DEVS models.
• Compiles and runs with most of the adevs-1.x test cases.

This library does not support

• Models based on the adevs-1.x cellSpace class
• Multi-threaded simulation (which some of the 1.x versions supported)
• The devssim and xdevssim classes.
  

To use the library, make sure that the adevs_v1_compat/include directory is included in the list of directories that your compiler will search. In every file that includes adevs-1.x headers, replace those with #include "adevs_v1_compat.h". Then rewrite the (hopefulyl small) piece of your code that uses the devssim or xdevssim class so that is uses the adevs-2.x adevs::Simulator<PortValue> class instead. Thats it!  Good luck 8-). The test cases provide some examples of how to use this backwards compatibility API.
