        "DESCRIPTION": {
            "content": "Dviselect  selects  pages  from a DVI file produced by TeX, creating a new DVI file usable by\nany of the TeX conversion programs, or even by dviselect itself.\n\nA range is a string of the form even, odd, or first:last where both first and  last  are  op‐\ntional  numeric  strings,  with  negative numbers indicated by a leading underscore character\n``''.  If both first and last are omitted, the colon may also be omitted, or may be replaced\nwith an asterisk ``*''.  A page range is a list of ranges separated by periods.   A  list  of\npages is described by a set of page ranges separated by commas and/or white space.\n\nDviselect  actually  looks  at  the  ten  count variables that TeX writes; the first of these\n(\\count0) is the page number, with \\count1 through \\count9 having varied  uses  depending  on\nwhich  macro  packages are in use.  (Typically \\count1 might be a chapter or section number.)\nA page is included in dviselect's output if all its \\count values match any one of the ranges\nlisted on the command line.  For example, the  command  ``dviselect  *.1,35:''  might  select\neverything  in chapter 1, as well as pages 35 and up.  ``dviselect 10:30'' would select pages\n10 through 30 (inclusive).  ``:43'' means everything up to and including page  43  (including\nnegative-numbered  pages).  To get all even-numbered pages, use ``even''; to get all odd-num‐\nbered pages, use ``odd''.  If a Table of Contents has negative page numbers, ``:1'' will se‐\nlect it.  Note that ``*'' must be quoted from the shell; the empty string is more  convenient\nto use, if harder to read.\n\nInstead  of  \\count  values, dviselect can also select by ``absolute page number'', where the\nfirst page is page 1, the second page 2, and so forth.  Absolute page numbers  are  indicated\nby a leading equal sign ``=''.  Ranges of absolute pages are also allowed: ``dviselect =3:7''\nwill  extract  the  third  through  seventh  pages.  Dot separators are not legal in absolute\nranges, and there are no negative absolute page numbers.  Even/odd specifiers,  however,  are\nlegal; ``dviselect =even'' selects every other page, starting with the second.\n\nMore precisely, an asterisk or an empty string implies no limit; an equal sign means absolute\npage  number  rather  than  \\counts; a leading colon means everything up to and including the\ngiven page; a trailing colon means everything from the given page on; the word ``even'' means\nonly even values shall be accepted; the word ``odd'' means only odd values shall be accepted;\nand a period indicates that the next \\count should be examined.  If fewer than 10 ranges  are\nspecified,  the  remaining  \\counts are left unrestricted (that is, ``1:5'' and ``1:5.*'' are\nequivalent).  A single number n is treated as if it were the range n:n.  An arbitrary  number\nof  page selectors may be given, separated by commas or whitespace; a page is selected if any\nof the selectors matches its \\counts or absolute page number.\n\nDviselect normally prints the page numbers of the pages selected; the  -s  option  suppresses\nthis.\n",

        "BUGS": {
            "content": "A  leading ``-'' ought to be allowed for negative numbers, but it is currently used as a syn‐\nonym for ``:'', for backwards compatibility.\n\nSection or subsection selection will sometimes fail, for the DVI file lists only  the  \\count\nvalues  that  were  active  when the page ended.  Clever macro packages can alleviate this by\nmaking use of other ``free'' \\count registers.  Chapters normally begin on new pages, and  do\nnot suffer from this particular problem.\n\nThe heuristic that decides which arguments are page selectors and which are file names is of‐\nten wrong.  Using shell redirection or the -i and -o options is safest.\n\nDviselect  does  not  adjust the parameters in the postamble; however, since these values are\nnormally used only to size certain structures in the output conversion programs, and the  pa‐\nrameters never need to be adjusted upward, this has not proven to be a problem.\n\nDVISELECT(1)",
