# Gnuplot package for OpenWrt.

# Adapted to support LibGGI video output by

#

# Todo for GGI support (svgalib works, so GGI is disabled for now)
#
# - After 21acf8eb423af24ca00835192239d50f2e4570a8 I once had proper plot
#   display from Octave (but didn't came back to the console afterwards).
#   Even after building again with mouse support, this isn't working any more.
#   Why?  Must be related to the 050-ggi-close.patch but that patch is doing
#   close to nothing.
#
# - Somebody seems to mess with the console/stdin.  Even when using
#   GGI_FBDEV_OPTIONS=-noinput and setting GGI_NEWVT.  Can be easily tested
#   when launching from ssh.
#
# - When using GGI_NEWVT in Octave, it seems like somebody is injecting text
#   or something into Octave's stdin or into the file handles Octave uses.  It
#   would abort with some strange error message noting that it doesn't know
#   some corrupted command name (stuff like "setset").  Very frightening.

define Package/gnuplot-gfx/Default/description
  Gnuplot  is a portable command-line driven graphing utility for linux, OS/2, 
  MS Windows, OSX, VMS, and many other platforms.  This version is compiled
  to use LibGGI as default terminal, allowing gnuplot to draw directly to
  the Linux framebuffer.
