#add dependencies
#dependencies contains a FSO per line
#for ghc     : prefix each FSO with -package-conf
#for ghc-pkg : prefix each FSO with -f or --package-conf (note the difference with ghc)
#both        : append with package.conf
#
#example: $(sort FSO1/dependencies FSO2/dependencies | uniq | sed 's|^|FSO/|; s|$|/package.conf|')

#no dependencies
