If not given, the fuzzer will\nread the file fuzzer.xml. It has the following XML format:\n\n    \u003cfuzzer\u003e\n     \u003coutputPath\u003e\u003c/outputPath\u003e\n     \u003cvalidFilesPath\u003e\u003c/validFilesPath\u003e\n     \u003cvalidFilesPattern\u003e\u003c/validFilesPattern\u003e\n     \u003cstartBytes\u003e\u003c/startBytes\u003e\n     \u003cfileExtension\u003e\u003c/fileExtension\u003e\n     \u003cfuzzOffset\u003e\u003c/fuzzOffset\u003e\n     \u003cfrequencyMean\u003e\u003c/frequencyMean\u003e\n     \u003cfrequencyStdDev\u003e\u003c/frequencyStdDev\u003e\n     \u003citerations\u003e\u003c/iterations\u003e\n    \u003c/fuzzer\u003e\n\n* outputPath - Path of the directory to store the generated file.\n* validFilesPath - Path of the directory containing files in a particular file\n  format. The fuzzer will randomly manipulate these files to generate its\n  test data.\n* startBytes - A hexadecimal string specifying the bytes to write at the\n  beginning of some of the generated files. Such files will contain random\n  data following the header.\n* fileExtension - File extension of the generated files.\n* fuzzOffset - Byte offset of the point where the fuzzer will modify the\n  bytes of the files located in _validFilesPath_.\n* frequencyMean - Mean of the frequency of changes, in bytes.\n* frequencyStdDev - Standard deviation of the frequency of changes, in bytes.\n* iterations - Number of files to generate. Each file will be named XXXXX.YYY\n  where XXXXX is a sequence of five or more digits and YYY is the file\n  extension given in _fileExtension_.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpeteroupc%2Ffuzzer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpeteroupc%2Ffuzzer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpeteroupc%2Ffuzzer/lists"}
