@NewPage
@Name      = Info
@Title     = Information and simple statistics
@Section   = Information
@Class     = Information
@Arguments = ifiles
@Operators = info infon map

@BeginDescription
This module writes information about the structure and contents 
of all input files to standard output.  All input files need to have 
the same structure with the same variables on different timesteps.
The information displayed depends on the chosen operator.
@EndDescription
@EndModule


@BeginOperator_info
@Title     = Dataset information listed by parameter identifier

@BeginDescription
Prints information and simple statistics for each field of all
input datasets. For each field the operator prints one line with 
the following elements:
@BeginItemize
@Item = Date and Time
@Item = Parameter identifier and Level
@Item = Size of the grid and number of Missing values
@Item = Minimum, Mean and Maximum \\
The mean value is computed without the use of area weights!
@EndItemize
@EndDescription
@EndOperator


@BeginOperator_infon
@Title     = Dataset information listed by parameter name

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


@BeginOperator_map
@Title     = Dataset information and simple map

@BeginDescription
Prints information, simple statistics and a map for each field of all input
datasets. The map will be printed only for fields on a regular lon/lat grid.
@EndDescription
@EndOperator


@BeginExample
To print information and simple statistics for each field of a dataset use:
@BeginVerbatim
   cdo infon ifile
@EndVerbatim
This is an example result of a dataset with one 2D parameter over 12 timesteps:
