/** Output specification for a linker run.
 *
 *  @param jsFile The JavaScript file a [[Linker]] writes to.
 *
 *  @param sourceMap The sourceMap file the linker writes to. A [[Linker]] may
 *      ignore this file. N.b. the standard linker will ignore it if
 *      [[StandardConfig.sourceMap]] is false. Further, a [[Linker]] must not
 *      fail if this is not set, but rather not write a source map (even if it
 *      is configured to write a source map).
 *
 *  @param sourceMapURI URI to reach the source map from the JavaScript file.
 *      This is typically a relative URI but is not required. A [[Linker]]
 *      should ignore this, if [[sourceMap]] is not set or source map production
 *      is disabled.
 *
 *  @param jsFileURI URI to reach the JavaScript file from the source map. This
 *      is typically a relative URI but is not required. A [[Linker]] may use
 *      this even if [[sourceMap]] is not set, but it is typically meaningless.
