WARNING: The current user does not have permission to create symbolic links, forcing pygcam to copy rather
than symlink files. This uses much more file space than using symlinks, but it works. To use pygcam more
efficiently, ask your System Administrator to give you permission to Create Symbol Links (using gpedit.msc)
See http://superuser.com/questions/104845/permission-to-make-symbolic-links-in-windows-7 for more info.
Set "GCAM.SymlinkWarning = False" in ~/.pygcam.cfg to suppress this message.

#
# - Allow config file itself to have a write func? Nah, need a per-trial version.
# - Copy config.xml to "exe" dir and modify it as the scenarios.xml file would have done.
# - Modify project.xml to call "gcam" step with "-C config.xml" so it takes it from exe dir.
#
# - Would it work as <InputFile name="../local-xml/base/config.xml"> ?
# Might need special tag like <InputFile name="__config__"> or a new tag,
# <ConfigFile>
# <WriteFunc>writeFuncs.configure</WriteFunc>
# </ConfigFile>
