@Name      = Sinfo
@Title     = Short information
@Section   = Information
@Class     = Information
@Arguments = ifiles
@Operators = sinfo sinfon

@BeginDescription
This module writes information about the structure of @file{ifiles} to standard output.
@file{ifiles} is an arbitrary number of input files. All input files need to have 
the same structure with the same variables on different timesteps.
The information displayed depends on the chosen operator.

@BeginOperator_sinfo
@Title     = Short information listed by parameter identifier

@BeginDescription
Prints short information of a dataset. The information is divided into
4 sections. Section 1 prints one line per parameter with the following 
information:
@BeginItemize
@Item = institute and source
@Item = timestep type
@Item = number of levels and z-axis number
@Item = horizontal grid size and number
@Item = data type
@Item = parameter identifier
@EndItemize
Section 2 and 3 gives a short overview of all grid and vertical coordinates.
And the last section contains short information of the time coordinate.

@EndOperator


@BeginOperator_sinfon
@Title     = Short information listed by parameter name

@BeginDescription
The same as operator @oper{sinfo} but using the name instead of the 
identifier to label the parameter.
@EndDescription
@EndOperator


@BeginExample
To print short information of a dataset use:
@BeginVerbatim
   cdo sinfon ifile
@EndVerbatim
This is the result of an ECHAM5 dataset with 3 parameter over 12 timesteps:
