Language: Ruby

View as text

# Scans your project for CSS and JS files and 
# runs them through the Yahoo Compression utility
# and then uploads the entire site to your web server via SCP.

# Install prerequisites:

# sudo gem install net-scp

# Download http://www.julienlecomte.net/yuicompressor/
# Create a bin/ folder and place the following files from the download into the folder:
#
# * yuicompressor-2.4.2.jar
# * rhino-1.6R7.jar
# * jargs-1.0.jar

# Configure your settings below and be sure
# to supply the proper path to the Yahoo compressor.  
# Set the COMPRESS flag to false to skip compression
