       makeconv - compile a converter table


       makeconv [ -h, -?, --help ] [ -c, --copyright ] [ -v, --verbose ] [ -d,
       --destdir destination ] convertertable ...


       makeconv converts the ICU converter table convertertable into a  binary
       file.  The binary file has the same base name as convertertable but has
       a .cnv  extension  (instead  of  the  typical  .ucm  extension  of  the
       convertertable  file).   This  binary file can then be read directly by
       ICU, or used by pkgdata(1) for incorporation into a larger  archive  or

       The  convertertable  must  be in the ICU ucm (Unicode Codepage Mapping)
       format in order to be understood by makeconv.  The ICU  ucm  format  is
       similar  to  the  IBM  NLTC  upmap/tpmap/rpmap  files.  Comments in the
       convertable are handled as follows. If a comment (starting with  a  ‘#’
       sign)  that  is after some text does contain the fallback indicator ‘|’
       then only the text starting with the ‘#’ sign, and  ending  before  the
       ‘|’  sign, is ignored.  Otherwise, or if the comment is the first thing
       on the line, the comment runs up to the end of the line.  This  special
       handling  of comments is to accomodate the practice of putting fallback
       information in comments in the strict IBM NLTC ucmap format.

       Note that new converters will be automatically found by ICU after their
       installation  in ICU’s data directory. They do not need to be listed in
       the convrtrs.txt(5) converters aliases file in order to be available to
       applications  using  ICU.  They do need to be listed there if one wants
       to give them aliases, or tags, though.


       -h, -?, --help
              Print help about usage and exit.

       -c, --copyright
              Include a copyright notice in the binary data.

       -v, --verbose
              Display extra informative messages during execution.

       -d, --destdir destination
              Set the  destination  directory  to  destination.   The  default
              destination  directory  is specified by the environment variable


       If  an  existing  converter  table  is  changed  and  recompiled  using
       makeconv,  the  resulting  binary file must be packaged in the same way
       that it was packaged initially. For example, if converters were grouped
       together  in  an archive or a library with pkgdata(1), then the archive
       or library must be rebuilt with the  new  binary  file.   A  standalone
       binary converter file will not take precedence over a packaged one.


       ICU_DATA  Specifies  the  directory  containing  ICU  data. Defaults to
                 ${prefix}/share/icu/4.2.1/.  Some tools in ICU depend on  the
                 presence  of the trailing slash. It is thus important to make
                 sure that it is present if ICU_DATA is set.
