.SH DESCRIPTION
.B icupkg
reads the input ICU
.B .dat
package file, modify it according to the options,
swap it to the desired platform properties (charset & endianness),
and optionally write the resulting ICU
.B .dat
package to the output file.
Items are removed, then added, then extracted and listed.
An ICU
.B .dat
package is written if items are removed or added,
or if the input and output filenames differ,
or if the
.BR "\-w\fP, \fB\-\-writepkg"
option is set.
.PP
If the input filename is "new" then an empty package is created.
If the output filename is missing, then it is automatically generated
from the input filename. If the input filename ends with an l, b, or e
matching its platform properties, then the output filename will
contain the letter from the
.BI "\-t\fP, \fB\-\-type"
option.
.PP
This tool can also be used to just swap a single ICU data file, replacing the
former icuswap tool. For this mode, provide the infilename (and optional
outfilename) for a non-package ICU data file.
Allowed options include
.BI "\-t\fP, \fB\-w\fP, \fB\-s\fP"
and
.BI \-d
.
The filenames can be absolute, or relative to the source/dest dir paths.
Other options are not allowed in this mode.
.SH OPTIONS
.TP
.BR "\-h\fP, \fB\-?\fP, \fB\-\-help"
Print help about usage and exit.
.TP
.BI "\-tl\fP, \fB\-\-type" " l"
Output for little-endian/ASCII charset family.
The output type defaults to the input type.
.TP
.BI "\-tb\fP, \fB\-\-type" " b"
Output for big-endian/ASCII charset family.
The output type defaults to the input type.
.TP
.BI "\-te\fP, \fB\-\-type" " e"
Output for big-endian/EBCDIC charset family.
The output type defaults to the input type.
.TP
.BR \-c\fP, \fB\-\-copyright
Include the ICU copyright notice in the resulting data.
.TP
.BI "\-C\fP, \fB\-\-comment" " comment"
Include the specified
.I comment
in the resulting data instead of the ICU copyright notice. 
.TP
.BI "\-a\fP, \fB\-\-add" " list"
Add items from the
.I list
to the package. The list can be a single filename with a
.B .txt
file extension containing a list of item filenames, or an ICU
.B .dat
package filename.
.TP
.BI "\-r\fP, \fB\-\-remove" " list"
Remove items from the
.I list
from the package. The list can be a single filename with a
.B .txt
file extension containing a list of item filenames, or an ICU
.B .dat
package filename.
.TP
.BI "\-x\fP, \fB\-\-extract" " list"
Extract items from the
.I list
from the package. The list can be a single filename with a
.B .txt
file extension containing a list of item filenames, or an ICU
.B .dat
package filename.
.TP
.BI "\-m\fP, \fB\-\-matchmode" " mode"
Set the matching mode for item names with wildcards.
.TP
.BI "\-s\fP, \fB\-\-sourcedir" " source"
Set the source directory to
.IR source .
The default source directory is the current directory.
.TP
.BI "\-d\fP, \fB\-\-destdir" " destination"
Set the destination directory to
.IR destination .
The default destination directory is the current directory.
.TP
.BI "\-l\fP, \fB\-\-list"
List the package items to stdout (after modifying the package).
.SH LIST FILE SYNTAX
Items are listed on one or more lines and separated by whitespace (space+tab).
Comments begin with
.B #
and are ignored. Empty lines are ignored. Lines where the first non-whitespace
character is one of "%&'()*+,-./:;<=>?_ are also ignored
to reserve for future syntax.
.PP
Items for removal or extraction may contain a single 
.B *
wildcard character. The 
.B *
matches zero or more characters. If
.BI "\-m\fP, \fB\-\-matchmode" " noslash"
is set, then the
.B *
character does not match the
.B /
character.
.PP
Items must be listed relative to the package, and the
.B "\fB\-\-sourcedir"
or the
.B "\fB\-\-destdir"
path will be prepended. The paths are only prepended to item
filenames while adding or extracting items, not to ICU .dat package or list
filenames.
.PP
Paths may contain
.B /
instead of the platform's file separator character and are converted as
appropriate.
