NAME

       makeconv - compile a converter table

SYNOPSIS

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

DESCRIPTION

       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 convert-
       ertable  file).   This binary file can then be read directly by ICU, or
       used by pkgdata(1) for incorporation into a larger archive or  library.

       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 con-
       vertable 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.

OPTIONS

       -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  des-
              tination  directory  is  specified  by  the environment variable
              ICU_DATA.

CAVEATS

       If an existing converter table is changed and  recompiled  using  make-
       conv,  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.

ENVIRONMENT

       ICU_DATA  Specifies  the  directory  containing  ICU  data. Defaults to
                 /usr/lib/icu/3.6/.  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.
