31 .B gensprep
|
|
jpayne@68
|
32 reads filtered RFC 3454 files and compiles their
|
|
jpayne@68
|
33 information into a binary form.

34 The resulting file,
|
|
jpayne@68
|
35 .BR <name>.icu ,
|
|

jpayne@68
|
37 .BR pkgdata (8)
|
|
jpayne@68
|
38 for incorporation into a larger archive or library.
