+.IR bundle " \.\.\."
+.SH DESCRIPTION
+.B derb
+reads the compiled resource
+.I bundle
+files passed on the command line and write them back in text form.
+The resulting text files have a
+.B .txt
+extension while compiled resource bundle source files typically have a 
+.B .res
+extension.
+.PP
+It is customary to name the resource bundles by their locale name,
+i.e. to use a local identifier for the
+.I bundle
+filename, e.g.
+.B ja_JP.res
+for Japanese (Japan) data, or
+.B root.res
+for the root bundle.
+This is especially important for
+.B derb
+since the locale name is not accessible directly from the compiled
+resource bundle, and to know which locale to ask for when opening
+the bundle.
+.B derb
+will produce a file whose base name is the base name of the compiled resource file itself.
+If the
+.BI "\-\-to\-stdout\fP, \fB\-c\fP"
+option is used, however, the text will be written on the standard output.
+.SH OPTIONS
+.TP
+.BR "\-h\fP, \fB\-?\fP, \fB\-\-help"
+Print help about usage and exit.
+.TP
+.BR "\-V\fP, \fB\-\-version"
+Print the version of
+.B derb
+and exit.
+.TP
+.BR "\-v\fP, \fB\-\-verbose"
+Display extra informative messages during execution.
+.TP
+.BR "\-A\fP, \fB\-\-suppressAliases"
+Don't follow aliases when producing output.
+.TP
+.BI "\-e\fP, \fB\-\-encoding" " encoding"
+Set the encoding used to write output files to
+.IR encoding .
+The default encoding is the invariant (subset of ASCII or EBCDIC)
+codepage for the system (see section
+.BR "INVARIANT CHARACTERS" ).
+The choice of the encoding does not affect the data, just their
+representation. Characters that cannot be represented in the
+.I encoding
+will be represented using
+.BI \eu "hhhh"
+escape sequences.
+.TP
+.BI "\-\-bom"
+Write a byte order mark (BOM) at the beginning of the file.
+.TP
+.BI "\-l\fP, \fB\-\-locale" " locale"
+Set the
+.I locale
+for the resource bundle, which is used both in the generated text and
+as the base name of the output file.
+.TP
+.BI "\-t\fP, \fB\-\-truncate" " \fR[ \fPsize\fR ]\fP"
+Truncate individual resources (strings or binary data) to
+.I size
+bytes. The default if
+.I size
+is not specified is
+.B 80
+bytes.
+.TP
+.BI "\-s\fP, \fB\-\-sourcedir" " source"
+Set the source directory to
+.IR source .
+The default source directory is the current directory.
+If 
+.B -
+is passed for
+.IR source ,
+then the
+.I bundle
+will be looked for in its default location, specified by
+the 
+.B ICU_DATA
+environment variable (or defaulting to
+the location set when ICU was built if 
+.B ICU_DATA
+is not set).
+.TP
+.BI "\-d\fP, \fB\-\-destdir" " destination"
+Set the destination directory to
+.IR destination .
+The default destination directory is specified by the environment variable
+.BR ICU_DATA
+or is the location set when ICU was built if 
+.B ICU_DATA
+is not set.
+.TP
+.BI "\-i\fP, \fB\-\-icudatadir" " directory"
+Look for any necessary ICU data files in
+.IR directory .
+For example, when processing collation overrides, the file
+.B ucadata.dat
+must be located.
+The default ICU data directory is specified by the environment variable
+.BR ICU_DATA .
+.TP
+.BI "\-c\fP, \fB\-\-to\-stdout"
+Write the disassembled
+.I bundle
+on standard output instead of into a file.
+.SH CAVEATS
+When the option
+.BI \-\-bom
+is used, the character
+.B U+FEFF
+is written in the destination
+.I encoding
+regardless of whether it is a Unicode transformation format (UTF) or not.
+This option should only be used with an UTF encoding, as byte order marks
+are not meaningful for other encodings.
+.SH INVARIANT CHARACTERS
+The
+.B invariant character set
+consists of the following set of characters, expressed as a standard POSIX
+regular expression:
+.BR "[a-z]|[A-Z]|[0-9]|_| |+|-|*|/" .
+This is the set which is guaranteed to be available regardless of code page.
+.SH ENVIRONMENT
+.TP 10
+.B ICU_DATA
+Specifies the directory containing ICU data. Defaults to
+.BR @thepkgicudatadir@/@PACKAGE@/@VERSION@/ .
+Some tools in ICU depend on the presence of the trailing slash. It is thus
+important to make sure that it is present if
+.B ICU_DATA
+is set.

+.IR bundle " \.\.\."
+.SH DESCRIPTION
+.B genrb
+converts the resource
+.I bundle
+source files passed on the command line to their binary form or to
+a Java source file for use with ICU4J.
+The resulting binary files have a
+.B .res
+extension while resource bundle source files typically have a 
+.B .txt
+extension. Java source files have a
+.B java
+extension and follow the ICU4J naming conventions.
+.PP
+It is customary to name the resource bundles by their locale name,
+i.e. to use a local identifier for the
+.I bundle
+filename, e.g.
+.B ja_JP.txt
+for Japanese (Japan) data, or
+.B root.txt
+for the root bundle.
+In any case,
+.B 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.
+.PP
+The binary files can be read directly by ICU, or used by
+.BR pkgdata (1)
+for incorporation into a larger archive or library.
+.SH OPTIONS
+.TP
+.BR "\-h\fP, \fB\-?\fP, \fB\-\-help"
+Print help about usage and exit.
+.TP
+.BR "\-V\fP, \fB\-\-version"
+Print the version of
+.B genrb
+and exit.
+.TP
+.BR "\-v\fP, \fB\-\-verbose"
+Display extra informative messages during execution.
+.TP
+.BI "\-e\fP, \fB\-\-encoding" " encoding"
+Set the encoding used to read input files to
+.IR encoding .
+The default encoding is the invariant (subset of ASCII or EBCDIC)
+codepage for the system (see section
+.BR "INVARIANT CHARACTERS" ).
+The encodings UTF-8, UTF-16BE, and UTF-16LE are automatically detected
+if a byte order mark (BOM) is present.
+.TP
+.BI "\-j\fP, \fB\-\-write\-java" " \fR[ \fPencoding\fR ]\fP"
+Generate a Java source code for use with ICU4J. An optional
+.I encoding
+for the Java file can be given.
+.TP
+.BI "\-s\fP, \fB\-\-sourcedir" " source"
+Set the source directory to
+.IR source .
+The default source directory is specified by the environment variable
+.BR ICU_DATA ,
+or the location set when ICU was built if 
+.B ICU_DATA
+is not set.
+.TP
+.BI "\-d\fP, \fB\-\-destdir" " destination"
+Set the destination directory to
+.IR destination .
+The default destination directory is specified by the environment variable
+.BR ICU_DATA
+or is the location set when ICU was built if 
+.B ICU_DATA
+is not set.
+.TP
+.BI "\-i\fP, \fB\-\-icudatadir" " directory"
+Look for any necessary ICU data files in
+.IR directory .
+For example, when processing collation overrides, the file
+.B ucadata.dat
+must be located.
+The default ICU data directory is specified by the environment variable
+.BR ICU_DATA .
+.SH INVARIANT CHARACTERS
+The
+.B invariant character set
+consists of the following set of characters, expressed as a standard POSIX
+regular expression:
+.BR "[a-z]|[A-Z]|[0-9]|_| |+|-|*|/" .
+This is the set which is guaranteed to be available regardless of code page.
+.SH ENVIRONMENT
+.TP 10
+.B ICU_DATA
+Specifies the directory containing ICU data. Defaults to
+.BR @thepkgicudatadir@/@PACKAGE@/@VERSION@/ .
+Some tools in ICU depend on the presence of the trailing slash. It is thus
+important to make sure that it is present if
+.B ICU_DATA
+is set.
