    Lib version is the "version" of the SWC format. Major number changes represent big (although not by definition incompatble) changes, such as bytecode format revs. Minor number changes are intended to represent easy-to-support modifications. The only universal rule is that the compiler will warn when a "future" major version is found in a SWC that's being read in. It's expected that incompatible changes will arise. Ad-hoc guard code will be added to implement those dividing lines. The way the code is currently laid out, these would probably be implemented in SWC.read(), but in any case they should be finable by looking at the callers of VersionInfo.getLibVersion().
  - Version 1.2: Add <keep-as3-metadata> container to catalog.xml to perserve metadata
  - Version 1.1: Add <digest> container to catalog xml for cross-domain rsls support. Add "signatureChecksum" attribute to "script" element.
  - Version 1.0: Initial version.

- buildMessage
```
public static String buildMessage()
```
- getBuild
```
public static String getBuild()
```
- getBuildLong
```
public static long getBuildLong()
```
  Get the build number as a long.
  
  Returns:
  
  build number as a long, 0 if the build number was not available.
- getRoyaleVersion
```
public static String getRoyaleVersion()
```
- getLibVersion
```
public static String getLibVersion()
```
- getCompilerName
```
public static String getCompilerName()
```
  The name of the compiler.
  
  Returns:
  
  name of the compiler.
- getCompilerVersion
```
public static String getCompilerVersion()
```
  The version of the compiler. Includes the major, minor, and nano versions separates by dots. For example, 4.7.0. The compiler version number comes from information from the manifest.mf file where as the Flex version number is hard-coded in this file.
  
  Returns:
  
  version of the compiler.
- getCompilerBuild
```
public static String getCompilerBuild()
```
  The build number of the compiler. Can be converted to a long. The compiler build number comes from information from the manifest.mf file where as the Flex build number comes from a properties file.
  
  Returns:
  
  the build number of the compiler.
- IsNewerLibVersion
```
public static boolean IsNewerLibVersion(String swcLibVersion,
                                        boolean compareMajorVersion)
```
  Parameters:
  
  swcLibVersion - - library version to compare with the current library version.
  
  compareMajorVersion - - if true, compare only the major versions. Otherwise compare both major and minor versions.
  
  Returns:
  
  true if the given library version is greater than the compiled in library version.
- compareVersions
```
public static int compareVersions(String version1,
                                  String version2,
                                  boolean compareMajorVersion)
```
  Compare two version strings that are in at "Major.minor" format. Examples) "1.0", "1.1"
  
  Parameters:
  
  version1 - first version
  
  version2 - second version
  
  compareMajorVersion - compare only the major versions, disregarding the minor version.
  
  Returns:
  
  zero if the versions are equal less than zero if version1 is less than version2 greater than zero if version1 is greater than version2
