main.cpp

/*
	MapMaker plugin
	Purpose:
	Get a pre-formatted string from arma and save it to a text file
	Retreive line from file and replace ; with , and add [ and ] to the end.
	A single procedure call returns a single line, maintain a file pointer and use getNext

	A function to create a file with filename
	Append a line to the current file
	Close the current file
	A function to open a file
	A function to list files
	A function to delete a file
*/

/*
	TO COMPILE ON LINUX WITH GCC

	replace the absolute paths with only relative ones like "libboost_system.a" if the system has static libraries installed

	TO COMPILE ON WINDOWS WITH MINGW(GCC)
