It is customary to name the resource bundles by their locale name, i.e. to use a local identifier for the bundle filename, e.g. ja_JP.txt for Japanese (Japan) data, or root.txt for the root bundle. In any case, genrb will produce a file whose base name is the name of the locale found in the resource file, not the base name of the resource file itself.

The binary files can be read directly by ICU, or used by pkgdata(1) for incorporation into a larger archive or library.

-h, -?, --help

Print help about usage and exit.

-V, --version

Print the version of genrb and exit.

-v, --verbose

Display extra informative messages during execution.

-e, --encoding encoding

Set the encoding used to read input files to encoding. The default encoding is the invariant (subset of ASCII or EBCDIC) codepage for the system (see section INVARIANT CHARACTERS). The encodings UTF-8, UTF-16BE, and UTF-16LE are automatically detected if a byte order mark (BOM) is present.

-j, --write-java [ encoding ]

Generate a Java source code for use with ICU4J. An optional encoding for the Java file can be given.

-s, --sourcedir source

Set the source directory to source. The default source directory is specified by the environment variable ICU_DATA, or the location set when ICU was built if ICU_DATA is not set.

-d, --destdir destination

Set the destination directory to destination. The default destination directory is specified by the environment variable ICU_DATA or is the location set when ICU was built if ICU_DATA is not set.

-i, --icudatadir directory

Look for any necessary ICU data files in directory. For example, when processing collation overrides, the file ucadata.dat must be located. The default ICU data directory is specified by the environment variable ICU_DATA.

ICU_DATA

Specifies the directory containing ICU data. Defaults to /usr/share/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.
