##############################################################################################
# Variables below can NOT reference other variables, manup will not expand them.
# So url=http://example.com/source/$name-$ver is not acceptable.
# Though all variables can be accessed in the build_* functions.
# The ONLY exception to this rule is the config=(...) array, where $prefix is available

# There are also more bash variables available than you see here.
# The /usr/local/lib/manup/functions.sh is sourced before this file. Check it out.
# There are also a few set by manup, like $prefix, $fakeroot, $is_installed, $installed_ver
# Visit http://manup.mreschke.com for details

# All variables and build_* function must be present, even if empty.
# Since a bash function cannot be empty, just put in some placeholder
# like null=nothing

# These files will be overwritten with every 'manup sync' command.
