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

@BeginDescription
This module writes information about the structure and contents 
of all input datasets to standard output. The information displayed 
depends on the chosen operator.
@EndDescription
@EndModule


@BeginOperator_info
@Title     = Dataset information listed by code number

@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 = Code number 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_infov
@Title     = Dataset information listed by variable name

@BeginDescription
The same as operator @oper{info} but using the name instead of the code
number to identify the variables.
@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 info ifile
@EndVerbatim
This is an example result of a dataset with one 2D variable over 12 time steps:
