/** | ||
* Parses extra properties files of UCD, and replaces the placeholders in | ||
* the given template source file with the generated conditions, then emits | ||
* .java files. For example, if the properties file has: | ||
* <blockquote> | ||
* 0009..000D ; Type (; Value) | ||
* 0020 ; Type (; Value) | ||
* 2000..200A ; Type (; Value) | ||
* </blockquote> | ||
* and the template file contains | ||
* <blockquote> | ||
* %%%Type(=Value)%%% | ||
* </blockquote> | ||
* then the generated .java file would have the following in place: | ||
* <blockquote> | ||
* (cp >= 0x0009 && cp <= 0x000D) || | ||
* cp == 0x0020 || | ||
* (cp >= 0x2000 && cp <= 0x200A); | ||
* </blockquote> | ||
* Note that those in parentheses in the properties file and the | ||
* template file are optional. | ||
* | ||
* Arguments to this utility: | ||
* args[0]: Full path string to the template file | ||
* args[1]: Full path string to the properties file | ||
* args[2]: Full path string to the generated .java file | ||
* args[3...]: Names of the property to generate the conditions | ||
