# Please read the comments below carefully and edit the file where necessary.
# Probably you will not have to make many changes.
# If on your system, the Python interpreter is not in /usr/bin (but in
# /usr/local/bin for example), you will have to change the first line
# of the file uligo.py accordingly.

#Gentoo Comment: Nothing in this file should make any changes to either the live filesystem, or to ${D}. All that stuff can be left to the ebuild.

                        # Look for .opt, .def files in $HOME/.uligo,
                        # or -if $HOME is not set- for /tmp/.uligo .
                        # You can replace /tmp with another directory that should
                        # be used as an alternative if $HOME is not set.
                        # It is very unlikely that you have to change this.

# f.write('d \n')       # Uncomment this if .dat files should be stored in the
                        # same directory as the corresp. sgf file.

# --- Gentoo Comment: I think we want an sgf directory, right? If not, just comment out the next line and modify the ebuild accordingly:

f.write('s /usr/share/sgf\n')                       
			# Uncomment (and change) this to set a new
                        # default path for sgf files
                        # (the directory you use must exist).
                        # This might make sense if you don't want to put the
                        # .sgf files in your bin directory.
                        # Leave it to make the sgf subdirectory of uligo's
                        # directory the default.

# create link to uligo.py

# ---Gentoo Comment: The following line would actually be "os.symlink('/usr/share/uligo03/uligo.py', '/usr/bin/uligo')" but I think Gentoo policy dictates that the ebuild itself should create all the symlinks, so we comment this out ->

#os.symlink('/usr/local/share/uligo03/uligo.py', '/usr/local/bin/uligo.py')
                        # This creates a link in /usr/local/bin pointing
                        # to uligo.py .
                        # If you put the uligo03 directory not in
                        # /usr/local/share, but somewhere else,
                        # you must change the first entry.
                        # You can change the second entry to put the link 
                        # somewhere else, but the link should be in a 
                        # directory which is in the PATH of the users. 
                        # The file uligo.py itself must stay in
                        # the uligo03 subdirectory where you unpacked it,
                        # because it needs to find the other files in
                        # that subdirectory.

# make uligo.py executable for everybody

#os.chmod('uligo.py', 0755) --- Gentoo Comment: Seems like we could actually leave this. But it's probably cleaner to let the ebuild handle this

# check if the python interpreter is in the 'right' place
