An options file is a text file that contains the options and values that
you would typically enter in a command prompt.
Options may appear on one line or on several lines.
You may not specify environment variables for path names.
You may comment out lines by prefixing a hash symbol (\f[CB]#\f[R]) to the
beginning of the line.
.PP
The following is an example of an options file for the \f[CB]jlink\f[R]
command:

.SH JLINK EXAMPLES
.PP
The following command creates a runtime image in the directory
\f[CB]greetingsapp\f[R].
This command links the module \f[CB]com.greetings\f[R], whose module
definition is contained in the directory \f[CB]mlib\f[R].
.IP

The following command creates a runtime image in the directory
compressedrt that\[aq]s stripped of debug symbols, uses compression to
reduce space, and includes French language locale information:
.IP
.nf
\f[CB]
jlink\ \-\-add\-modules\ jdk.localedata\ \-\-strip\-debug\ \-\-compress=2\ \-\-include\-locales=fr\ \-\-output\ compressedrt
\f[R]
.fi
.PP
The following example compares the size of the runtime image
\f[CB]compressedrt\f[R] with \f[CB]fr_rt\f[R], which isn\[aq]t stripped of
debug symbols and doesn\[aq]t use compression:
.IP
.nf
\f[CB]
jlink\ \-\-add\-modules\ jdk.localedata\ \-\-include\-locales=fr\ \-\-output\ fr_rt

du\ \-sh\ ./compressedrt\ ./fr_rt

The following example lists the providers that implement
\f[CB]java.security.Provider\f[R]:
.IP
.nf
\f[CB]
jlink\ \-\-suggest\-providers\ java.security.Provider

Suggested\ providers:

The following example creates a custom runtime image named
\f[CB]mybuild\f[R] that includes only \f[CB]java.naming\f[R] and
\f[CB]jdk.crypto.cryptoki\f[R] and their dependencies but no other
providers.
Note that these dependencies must exist in the module path:
.IP
.nf
\f[CB]
jlink\ \-\-add\-modules\ java.naming,jdk.crypto.cryptoki\ \-\-output\ mybuild
\f[R]
.fi
.PP
The following command is similar to the one that creates a runtime image
named \f[CB]greetingsapp\f[R], except that it will link the modules
resolved from root modules with service binding; see the
\f[B]\f[BC]Configuration.resolveAndBind\f[B]\f[R] method.
