/**
 * @file sddsinterpset.c
 * @brief Perform multiple interpolations on SDDS data sets.
 *
 * @details
 * This program reads an input SDDS file containing references to multiple data files.
 * For each referenced data file, it performs interpolation based on specified parameters
 * and writes the results to an output SDDS file. The interpolation behavior can be customized
 * using various command-line options.
 *
 * @section Usage
 * ```
 * sddsinterpset [<input>] [<output>]
 *               [-pipe=[input][,output]]
 *               [-order=<number>]
 *               [-verbose]
 *               [-data=fileColumn=<colName>,interpolate=<colName>,functionof=<colName>,column=<colName> | atValue=<value>]
 *               [-majorOrder=row|column]
 *               [-belowRange={value=<value>|skip|saturate|extrapolate|wrap}[,{abort|warn}]]
 *               [-aboveRange={value=<value>|skip|saturate|extrapolate|wrap}[,{abort|warn}]]
 * ```
 *
 * @section Options
 * | Option              | Description                                                                 |
 * |---------------------|-----------------------------------------------------------------------------|
 * | `-pipe`             | Use standard SDDS Toolkit pipe options for input and output.               |
 * | `-order`            | Specify the order of the polynomials used for interpolation.                |
 * | `-verbose`          | Print detailed processing messages.                                        |
 * | `-data`             | Define data interpolation parameters.                                      |
 * | `-majorOrder`       | Specify data ordering for output: `row` or `column`.                       |
 * | `-belowRange`       | Define behavior for out-of-range points below data range.                  |
 * | `-aboveRange`       | Define behavior for out-of-range points above data range.                  |
 *
 * @subsection Incompatibilities
 * - The `column` and `atValue` options within `-data` are mutually exclusive; only one can be specified per invocation.
