int main ( )

//****************************************************************************80
//
//  Purpose:
//
//    MAIN is the main program for FILE_NAME_SEQUENCE_TEST.
//
//  Discussion:
//
//    FILE_NAME_SEQUENCE_TEST tests the FILE_NAME_SEQUENCE library.
//
//    There are situations such as animations or parallel processing in which
//    it is necessary to generate a sequence of file names which include
//    an embedded index that increases.  A simple example might be
//
//      "fred0.txt", "fred1.txt", "fred2.txt"
//
//    A side issue arises when the number of files is large enough that the
//    number of digits in the index will vary.  Thus, if we are going to have
//    15 files, do we want to number them as
//
//      "fred00.txt" through "fred14.txt"
//
//    which means, for one thing, that they will alphabetize properly, or
//    will we be satisfied with
//
//      "fred0.txt" through "fred14.txt" ?
