# This program attempts to run configure with the correct build target
# and type based on the pwd.
# example: ~/rockbox/sansae200 is the build dir, it would run configure
# for the sansae200 normal build target.
# ~/rockbox/sansae200-sim for the e200 sim build (-boot for bootloader)
# ~/rockbox/sim/sansae200 for e200 sim build. (replace sim with boot is also possible)
# The full shortname is not required, each target name is checked and the first
# possible match is used.

# This script must be placed in the same directory as configure and builds.pm
#
