/**
 * @file sddsconvertlogonchange.c
 * @brief Converts SDDS log-on-change files with various configurable options.
 *
 * This program processes SDDS (Self Describing Data Sets) input files and converts them
 * based on specified command-line options. It supports binary and ASCII output formats,
 * floating and double precision, snapshotting at specific epoch times, piping input/output,
 * filtering by time intervals, and retaining or deleting specific columns based on patterns.
 *
 * Usage:
 *   sddsconvertlogonchange [<input-file>] [<output-file>]
 *     [-pipe=[input][,output]]
 *     [-binary | -ascii]
 *     [-double | -float]
 *     [-minimumInterval=<seconds>]
 *     [-snapshot=<epochtime>]
 *     [-time=[start=<epochtime>][,end=<epochtime>]]
 *     [-delete=<matching-string>[,...]]
 *     [-retain=<matching-string>[,...]]
 *
 * Options:
 *   -pipe            Configure piping for input and/or output.
 *   -binary          Output in binary format.
 *   -ascii           Output in ASCII format.
 *   -double          Use double precision for numerical data.
 *   -float           Use single precision (float) for numerical data.
 *   -minimumInterval Specify the minimum time interval between data points.
 *   -snapshot        Take a snapshot at the specified epoch time.
 *   -time            Filter data within the specified start and end epoch times.
 *   -delete          Delete columns matching the given patterns.
 *   -retain          Retain only columns matching the given patterns.
