                        required to build are missing.  This option over-rides
                        these checks and attempts a build anyway.
          --no-cleanup  By default any temporary source, build and package
                        directories will be deleted once the package is built.
                        This option prevents those files from being removed.

# -- PATENT ALERT! --
# MPlayer source contains an internal copy of 'libdvdcss' for reading DVD's.
# This is considered illegal software in some countries.
# Also, MPLayer can be built with MP3 (lame) and AMR audio encoders
# (needed for FLV and .3GP videos) but these libraries are 'contaminated'
# with patents from Fraunhofer and GGP.
# Also, the AAC encoder has patent issues.
# The Slackware package is built with "USE_PATENTS=NO" i.e. without using
# the lame mp3, faac, AMR and dvdcss libraries.
# This also means that this creates a version of MPlayer that is unable
# to play encrypted DVD's (which is most DVD's on the market). If it is
# allowed in your country to use libdvdcss, this is not a big problem though.
# Install a libdvdcss package and it will be picked up automatically by
# MPlayer's internal libdvdread library, so that MPlayer will again be able
# to play encrypted DVD's.
#
# If you have licenses to use the code, and/or the patents do not apply in
# your region, and you take all legal responsibility, you may wish to build
# MPlayer with the option USE_PATENTS=YES which will include potentially
# patent-encumbered code.
# ---------------------------------------------------------------------------
USE_PATENTS=${USE_PATENTS:-"YES"}

# MPlayer will try to use one of the TrueType fonts present on the target
# system for it's On Screen Display (OSD) font.
# Slackware 13.0 ships with the Vera and DejaVu fonts, you may want to add
# more fonts to this list. The first font found will be used by creating a
# symbolic link "/usr/share/mplayer/subfont.ttf" to it.
# The use of bitmapped fonts is considered deprecated, but you can still use
# those if you want. Read http://www.mplayerhq.hu/DOCS/HTML/en/fonts-osd.html
# if you want to know more about OSD font configuration.
