What would you like to do?
A wrapper script for Waf, just like Gradle.
#!/usr/bin/env python
# This Python script allows you to create tiny custom Waf distributions
# for each project you have. It's very similar to Gradle's wrapper scripts.
# Your mini Waf distribution can be customized using the variables at the top
# of the script.

# To install a plugin with your Waf distribution, simply add a tuple
# to this list with the plugin name and HTTP/HTTPS link to the plugin
# file.

# For example:
# ('eclipse', 'http://waf.googlecode.com/git/waflib/extras/eclipse.py'),
]
# Don't modify these! :P
