# publish.rb

#

# This script publishes the ev3dev website to the gh-pages branch of your

# personal fork. This allows you to share a preview of your changes with others.

#

# Usage: ./publish.rb { <gh-user> | <gh-url> | --test '<command>' }

#

# <gh-user> is your github user name. This is short for

# "git@github.com:<gh-user>/ev3dev.github.io.git"

#

# <gh-url> is the url for your fork on GitHub. For example, if you don't want

# to use ssh, then pass "https://github.com/<gh-user>/ev3dev.github.io.git"

# as the argument.

#

# --test '<command>' will run <command> in a shell and return the result. The

# working directory will be a temporary directory containing the fixed up files.

#

# Use BASENAME environment variable to override basename. Use "@TMP@" as a

# placeholder for the temporary directory that is created.
