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/57.1/. 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.
