# configuration of installation directories:
# * [l]rundir refers to the "Mined runtime support library" -
#   it contains the online help file, auxiliary scripts (some of which 
#   might actually be installed in .../bin, too), configuration samples etc.
# * [l]docdir is optional and refers to the mined web documentation 
#   (a copy of the mined home page).

# directories for target "make install"
prefix	= $(root)/usr
bindir	= $(prefix)/bin
mandir	= $(prefix)/share/man
rundir	= $(prefix)/share/mined
docdir	= $(prefix)/share/doc/mined

lprefix	= $(root)/usr
lbindir	= $(lprefix)/bin
lmandir	= $(lprefix)/share/man

# * prefer libtermcap over libncurses so on older systems 
#   (cygwin 1.5 before final terminfo update) the stand-alone binary 
#   will work with only cygwin1.dll (cygncurses*.dll not needed)
# * consider latest version of cygncurses dll as last resort so on 
#   newer systems (~ cygwin 1.7) compilation does not need ncurses-devel
# * static linking of ncurses would be another option; it's used for the 
#   stand-alone package version via a special target
