# We need to make our own copy of the eclipse platform in order to

# build against it.  We do this since the build root might already

# contain a copy of the plugin we are building -- and the eclipse

# releng scripts fail in this situation.  We put this script in the

# eclipse core so that it is easy to use from other spec files.

# Arguments are:

# * directory where results should end up (script will make it)

# * base location of eclipse platform install

# * an optional string that is used to select non-platform

#   plugins and features.  At present if a plugin or feature has

#   this as a substring, it will be included.  You need only run

#   this script once, it will link both the platform and the other

#   optionally-selected parts in a single invocation.

# Test to see if the minimum arguments

# are specified
