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

@BeginOperator_sinfo
@Title     = Short dataset information listed by code number

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

@EndOperator


@BeginOperator_sinfov
@Title     = Short dataset information listed by variable name

@BeginDescription
The same as operator @oper{sinfo} but using the name instead of the code number
and parameter table to identify the variables.
@EndDescription
@EndOperator


@BeginExample
To print short information of a dataset use:
@BeginVerbatim
   cdo sinfo ifile
@EndVerbatim
This is the result of an ECHAM5 dataset with 3 variables over 12 time steps:
