 # For the unfamiliar, Visual Studio ships with a batch file which sets up the
 # environment variables you need to be able to run visual studio tools from a
 # command prompt.
 #
 # This pluguin was written in response to someone that wanted to know how you
 # could run Sublime and have it have the visual studio environment already set
 # up.
 #
 # This plugin will use a subprocess to execute the batch file in the background
 # and then issue the 'set' command to get the command interpreter to output the
 # state of the environment before it exits.
 #
 # This output is gathered and parsed to come up with a dictionary similar to
 # the environ table that python uses. From here we can easily detect what new
 # environment variables were added and the values of those that changed, and
 # set them as appropriate.
 #
 # As written Sublime needs to be restarted  in order to execute the batch file
 # again. A more elegant solution would be to save the environment prior to
 # modifying it so that it could be restored and a new environment applied.

 # To use this, you need to specify a setting in your user preferences named
 # 'vc_vars_cmd' which should contain a complete path to the batch file you want
 # to execute. Optionally you can also specify 'vc_vars_arch', which will be
 # passed as a command line argument to the batch file executed. Remember that
 # the preferences are JSON, so you need to quote all path separators.
