# This script is responsible for saving the current configuration into a
# sample to be used later on as a pre-configured target.

# What we need to save:
#  - the .config file
#  - the uClibc .config file if uClibc selected
#  - info about who reported the sample

# Parse the tools' paths configuration
. "${CT_LIB_DIR}/paths.mk"

# We'll need the stdout later, save it
exec 7>&1

# Don't care about any log file
exec >/dev/null

# Parse the configuration file

# Parse architecture and kernel specific functions

# re-parse them:
