        6.1 Including WEB links
        Incorporating web links is easy, but the work went into an HTML file.
        Web links are included in the rest of the document, as shown in the following example.
        Users who draw information from PDF files are encouraged to visit the following example page: http://www.pdf-htm-ndx.info .
        The web address must be separated from the rest of the text, on the left and right, with at least one space.
        Therefore, in the example above, the dot at the end of the sentence is separated from the web address.
        The name of the web address that will be displayed in the HTML document will be the web address itself.

        7.1 AUTOMATED EDITING THE STRUCTURE OF TXT DOCUMENTS
        
        7.2 INTRODUCTION
        The program is intended for users who want to quickly and easily create a structured TXT file (document).
        At the same time as creating a new TXT file structure, the program also creates an HTML output file.
        The structure of the file is determined by the numbering of chapters and subchapters.
        Almost any editor can be used to create such a file, MS NOTEPAD is also sufficient.
        It is highly recommended that TXT files be written in UTF-8 format.
        This instruction was created entirely using MS NOTEPAD and formatted with the Windows console program TXT_IN.
        The program is free and users can use it only for their personal and non-commercial use.
        The program is available at the following link: http://www.txt-indent.info/txt_in.7z 
        A brief description of how TXT_IN works is below.
        
        7.3 CREATION OF CHAPTERS AND SUBCHAPTERS
        Chapters are marked exclusively by multilevel numbering.
        The format of this numbering is n1.n2.n3 ...
        
            7.3.1 Marking of chapters
            The chapters on the first level are marked n1. , a dot at the end is mandatory.
            The chapters of the second level are marked n1.n2, the third level n1.n2.n3 and so on.
            There is no dot for the last chapter numeric code, code n1.n2.n3. is wrong.
            The correct chapter designation on the third level is therefore n1.n2.n3 , without a dot at the end.
            The chapter label is followed by one or more spaces and the title of the chapter.
            The content of the chapter is written in the following lines under the chapter mark.
            The content of the chapter on the left edge is aligned with the chapter mark.
            Long lines of text are not printed separately, so they are not recommended.
            There are some such examples in this guide as well.
            Whole line spacing remains even after renumbering.
            
            7.3.2 Numbering and renumbering of chapters
            The label of the first chapter in the file has a special meaning, as it defines the highest level of all chapters.
            The level of the first chapter in the file MUST BE the first level labeled n1., but can also be n2, and so on.
            The essential functionality of the program is to renumber the chapters by levels and indent them accordingly.
            In this case, also the chapters marked as k1., l1 or m1. after renumbering, they stay first level, but submit to the number defined by the first chapter.
            So instead of k1. get the designation k2. or even k9.
            When users create chapters at the first and other levels (sub-levels), they often decide to arrange the chapters differently than they numbered at the beginning.
            Chapters of the first level are renumbered according to the position in the structure of the file (document).
            Other chapter level is determined by the current label, which changes depending on the position of the chapter in the file structure.
            For example, if a chapter has the designation n1.n2 (second-level chapter), it changes to k1.k2 or even l1.l2.l3...after renumbering.
            
        7.4 INCLUDING WEB LINKS
        Incorporating web links is easy, but the work went into an HTML file.
        Web links are included in the rest of the document, as shown in the following example.
        Users who draw information from PDF files are encouraged to visit the following example page: http://www.pdf-htm-ndx.info .
        The web address must be separated from the rest of the text, on the left and right, with at least one space.
        Therefore, in the example above, the dot at the end of the sentence is separated from the web address.
        The name of the web address that will be displayed in the HTML document will be the web address itself.

        7.5 CONVERSION TO HTML FORMAT
        At the same time as creating a new TXT file structure, the program also creates an HTML output file.
        To distinguish output TXT and HTML files from input files, an "_indent" extension is added to the name.
        The program does not offer output with the extension "_indent" in the list of possible input files at startup.
        If the user needs both a file and an input TXT file, he must copy and rename it.
