NAME

       gensprep - compile StringPrep data from files filtered by filterRFC3454.pl

SYNOPSIS

       gensprep [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright ] [ -s, --sourcedir source
       ] [ -d, --destdir destination ]

DESCRIPTION

       gensprep reads filtered RFC 3454 files and compiles their information into a binary  form.
       The  resulting  file,  <name>.icu, can then be read directly by ICU, or used by pkgdata(8)
       for incorporation into a larger archive or library.

       The files read by gensprep are described in the FILES section.

OPTIONS

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

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

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

       -s, --sourcedir source
              Set the source directory to source.  The default source directory is  specified  by
              the environment variable ICU_DATA.

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

ENVIRONMENT

       ICU_DATA  Specifies    the    directory    containing    ICU     data.     Defaults     to
                 ${prefix}/share/icu/52.1/.   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.

FILES

       The  following  files  are  read  by  gensprep  and are looked for in the source /misc for
       rfc3454_*.txt files and in source /unidata for NormalizationCorrections.txt.

       rfc3453_A_1.txt     Contains  the  list  of  unassigned  codepoints  in  Unicode   version
                           3.2.0....

       rfc3454_B_1.txt     Contains  the  list  of  code  points  that  are  commonly  mapped  to
                           nothing....

       rfc3454_B_2.txt     Contains the list of mappings for casefolding  of   code  points  when
                           Normalization form NFKC is specified....

       rfc3454_C_X.txt     Contains the list of code points that are prohibited for IDNA.

       NormalizationCorrections.txt
                           Contains the list of code points whose normalization has changed since
