# Usage: ./logger.sh theloggfile acommand arg1 arg2

#

# Execute acommand with args, in such a way that

# both stdout and stderr from acommand are appended to

# theloggfile.

#

# Preserve stdout and stderr, so that the stdout

# from logger.sh is the same from acommand and equally

# for stderr.

#

# Propagate the result code from acommand so that

# ./logger.sh exits with the same result code.

# Create a temporary directory to store the result code from

# the wrapped command.
