/* /////////////////////////////////////////////////////////////////////////
 * InetSTL version
 *
 * The libraries version information is comprised of major, minor and revision
 * components.
 *
 * The major version is denoted by the _INETSTL_VER_MAJOR preprocessor symbol.
 * A changes to the major version component implies that a dramatic change has
 * occurred in the libraries, such that considerable changes to source dependent
 * on previous versions would need to be effected.
 *
 * The minor version is denoted by the _INETSTL_VER_MINOR preprocessor symbol.
 * Changes to the minor version component imply that a significant change has
 * occurred to the libraries, either in the addition of new functionality or in
 * the destructive change to one or more components such that recomplilation and
 * code change may be necessitated.
 *
 * The revision version is denoted by the _INETSTL_VER_REVISIO preprocessor
 * symbol. Changes to the revision version component imply that a bug has been
 * fixed. Dependent code should be recompiled in order to pick up the changes.
 *
 * In addition to the individual version symbols - _INETSTL_VER_MAJOR,
 * _INETSTL_VER_MINOR and _INETSTL_VER_REVISION - a composite symbol _INETSTL_VER
 * is defined, where the upper 8 bits are 0, bits 16-23 represent the major
 * component,  bits 8-15 represent the minor component, and bits 0-7 represent
 * the revision component.
 *
 * Each release of the libraries will bear a different version, and that version
 * will also have its own symbol: Version 1.0.1 specifies _INETSTL_VER_1_0_1.
 *
 * Thus the symbol _INETSTL_VER may be compared meaningfully with a specific
 * version symbol, e.g. #if _INETSTL_VER >= _INETSTL_VER_1_0_1
