1038 dnl Most "modern" terminal emulators are based to some degree on VT100, and
1039 dnl should support line-drawing.  Even with Unicode.  There is a problem.
1040 dnl
1041 dnl While most of the VT100 graphics characters were incorporated into Unicode,
1042 dnl all of those were combined into a page of useful graphics characters.
1043 dnl
1044 dnl So far, so good.
1045 dnl
1046 dnl However, while they are useful, there are other considerations.  CJK
1047 dnl is (because of poor device resolution) often rendered as double-width
1048 dnl characters.  So... for these generally-useful characters, what should
1049 dnl be the width (to make them consistent with adjacent characters)?
1050 dnl
1051 dnl The obvious choice would have been to make this locale-dependent, and use
1052 dnl wcwidth() to tell applications what the actual width is.  That was too
1053 dnl obvious.  Instead, we have a slew of "ambiguous-width" characters.
1054 dnl See for example
1055 dnl             http://www.unicode.org/reports/tr11/tr11-29.html
1056 dnl             http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
1057 dnl
1058 dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
1059 dnl more than 22,000 characters, with 1281 of those as ambiguous-width.  For
1060 dnl instance, it lists half (44/96) of the Latin-1 characters as
1061 dnl ambiguous-width.  Also, all of the box-characters at 0x2500 are ambiguous.
1062 dnl
1063 dnl What this means for the implementor is that on some systems wcwidth() can
1064 dnl give bad advice.  On Solaris, some of the ambiguous widths are returned as
1065 dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
1066 dnl characters).  These do not necessarily match the behavior of the terminal
1067 dnl emulator.  xterm, for instance, does an optional startup check to find if
1068 dnl this problem (or similar) exists with the system's locale tables, rejecting
1069 dnl them if they are too unreliable.

4323 dnl Option to allow user to override automatic configuration of manpage format.
4324 dnl There are several special cases:
4325 dnl
4326 dnl     gzip - man checks for, can display gzip'd files
4327 dnl     compress - man checks for, can display compressed files
4328 dnl     BSDI - files in the cat-directories are suffixed ".0"
4329 dnl     formatted - installer should format (put files in cat-directory)
4330 dnl     catonly - installer should only format, e.g., for a turnkey system.
4331 dnl
4332 dnl There are other configurations which this macro does not test, e.g., HPUX's
4333 dnl compressed manpages (but uncompressed manpages are fine, and HPUX's naming
4334 dnl convention would not match our use).
