First attempt for python 3 compatibility.

ioannis@48	1	""" Sample script to convert licel files to SCC netcdf format.
ioannis@48	2
ioannis@48	3	The script assumes the following things:
ioannis@48	4
ioannis@48	5	1. You have already installed the atmospheric_lidar module (e.g. using pip).
ioannis@48	6	2. You have create a class in a file "lilas" describing your system (described the readme file).
ioannis@48	7	If you want to use it for a different system you need to change the script to use your own class
ioannis@48	8
ioannis@48	9	Run the script using: python convert_lilas.py <your options>
ioannis@48	10
ioannis@48	11	Examples
ioannis@48	12	--------
ioannis@48	13	# This will read all files starting with "l" from "my_dir".
ioannis@48	14	# It will guess the measurement ID based on the date of the files, and will assume measurement number 00.
ioannis@48	15	# For example, the new measurment id could be 20120101mb00
ioannis@48	16	python convert_lilas.py my_dir l*.
ioannis@48	17
ioannis@48	18	# This will use the measurement id you defined.
ioannis@48	19	python convert_lilas.py my_dir l*. -m 20120204mb32 # It will create the file 20120204mb32.nc
ioannis@48	20
ioannis@48	21	Help string
ioannis@48	22	-----------
ioannis@48	23	# To get this, run: python convert_lilas.py -h
ioannis@48	24	usage: convert_lilas.py [-h] [-m MEASUREMENT_ID] [-n MEASUREMENT_NUMBER]
ioannis@48	25	[directory] [searchstring]
ioannis@48	26
ioannis@48	27	positional arguments:
ioannis@48	28	directory Directory with licel files.
ioannis@48	29	searchstring Processing system id.
ioannis@48	30
ioannis@48	31	optional arguments:
ioannis@48	32	-h, --help show this help message and exit
ioannis@48	33	-m MEASUREMENT_ID, --measurement_id MEASUREMENT_ID
ioannis@48	34	The new measurement id
ioannis@48	35	-n MEASUREMENT_NUMBER, --measurement_number MEASUREMENT_NUMBER
ioannis@48	36	The measurement number for the date, if no id is
ioannis@48	37	provided
