1. 两种方式：
（1）plugin:实例在:C:Program FilesAutodeskmaya2015devkitplug-ins
（2）standalone API application：C:Program FilesAutodeskmaya2015devkitapplications
2. plugin
3. Maya API application:
In your plug-in directory, create 3 folders: plug-ins, scripts, and icons.
Place your plug-in files in the /plug-ins folder.
If your plug-in contains scripts, place your scripts files in the /scripts folder.
If your plug-in contains icons, place your icon files in the /icons folder.
Define the following environment variables in a file called Maya.env:
- MAYA_PLUG_IN_PATH - directory to search for plug-ins. Set this to your /plug-ins folder.
- MAYA_SCRIPT_PATH - directory to search for MEL and Python scripts. Set this to your /scripts folder.
- XBMLANGPATH - directory to search for icons. Set this to your /icons folder.
Maya.env文件存储的位置在各个环境下都不一样，可以参看帮助。Using Maya.env makes it easy to set up the same runtime environment on another system by simply copying the file.也可以用命令行直接设置这些环境变量。
目前好像用不上，ICON什么的。再说。
