SWIG的简介
SWIG是一种软件开发工具，它将C和C++编写的程序与各种高级编程语言连接起来。SWIG用于不同类型的目标语言，包括常见的脚本语言，如Javascript、Perl、PHP、Python、Tcl和Ruby。支持的语言列表还包括非脚本语言，如C#，D，Go language，Java，包括Android，Lua，OCaml，Octave，Scilab和R。还支持几种解释和编译的Scheme实现（Guile，MzScheme/Racket）。
SWIG最常用于创建高级解释或编译的编程环境、用户界面，以及作为测试和原型化C/C++软件的工具。SWIG通常用于解析C/C++接口，并生成用于上述目标语言调用C/C++代码所需的“胶粘代码”。SWIG还可以XML格式导出解析树。SWIG是自由软件，SWIG生成的代码与商业和非商业项目都兼容。

-cppext <ext> - Change file extension of generated C++ files to <ext>
(default is cxx)
-copyright - Display copyright notices
-debug-classes - Display information about the classes found in the interface

-debug-lsymbols - Display target language layer symbols
-debug-tags - Display information about the tags found in the interface
-debug-template - Display information for debugging templates
-debug-top <n> - Display entire parse tree at stages 1-4, <n> is a csv list of stages
-debug-typedef - Display information about the types and typedefs in the interface
-debug-typemap - Display typemap debugging information
-debug-tmsearch - Display typemap search debugging information
-debug-tmused - Display typemaps used debugging information
-directors - Turn on director mode for all the classes, mainly for testing
-dirprot - Turn on wrapping of protected members for director classes (default)
-D<symbol> - Define a symbol <symbol> (for conditional compilation)
-E - Preprocess only, does not generate wrapper code
-external-runtime [file] - Export the SWIG runtime stack
-fakeversion <v>- Make SWIG fake the program version number to <v>
-fcompact - Compile in compact mode
-features <list>- Set global features, where <list> is a comma separated list of
features, eg -features directors,autodoc=1
If no explicit value is given to the feature, a default of 1 is used

-includeall - Follow all #include statements
-l<ifile> - Include SWIG library file <ifile>
-macroerrors - Report errors inside macros
-makedefault - Create default constructors/destructors (the default)
-M - List all dependencies
-MD - Is equivalent to `-M -MF <file>', except `-E' is not implied
-MF <file> - Generate dependencies into <file> and continue generating wrappers
-MM - List dependencies, but omit files in SWIG library
-MMD - Like `-MD', but omit files in SWIG library
-module <name> - Set module name to <name>
-MP - Generate phony targets for all dependencies
-MT <target> - Set the target of the rule emitted by dependency generation

-O - Enable the optimization options:
-fastdispatch -fvirtual
-o <outfile> - Set name of C/C++ output file to <outfile>
-oh <headfile> - Set name of C++ output header file for directors to <headfile>
-outcurrentdir - Set default output dir to current dir instead of input file's path
-outdir <dir> - Set language specific files output directory to <dir>
-pcreversion - Display PCRE version information
-small - Compile in virtual elimination and compact mode
-swiglib - Report location of SWIG library and exit
-templatereduce - Reduce all the typedefs in templates
-v - Run in verbose mode
-version - Display SWIG version number
-Wall - Remove all warning suppression, also implies -Wextra
-Wallkw - Enable keyword warnings for all the supported languages

-Wextra - Adds the following additional warnings: 202,309,403,405,512,321,322
-w<list> - Suppress/add warning messages, eg -w401,+321 - see Warnings.html
-xmlout <file> - Write XML version of the parse tree to <file> after normal processing
Options can also be defined using the SWIG_FEATURES environment variable, for example:
$ SWIG_FEATURES="-Wall"
$ export SWIG_FEATURES
$ swig -python interface.i
is equivalent to:
$ swig -Wall -python interface.i
Arguments may also be passed in a file, separated by whitespace. For example:
$ echo "-Wall -python interface.i" > args.txt
$ swig @args.txt
Note: 'swig -<lang> -help' displays options for a specific target language.
