ASenvPropertyReaderpublic class ASenvPropertyReader extends Object | Class ASenvPropertyReader
This class converts the envrionment variables stored in asenv.conf (UNIX)
or asenv.bat (WINDOWS) into their equivalent system properties.
This means that a number of system properties with fixed values do
not have to be passed on the java command line using -D. |

Iterate through the lines of asenv.conf or asenv.bat and convert to
system properties.

| | private void | setSystemProperty(java.lang.String line)Method setSystemProperty
Parses a single line of asenv.conf or asenv.bat and attempt to
set the corresponding system property. Note that if the system
property is already set (e.g. via -D on the command line), then
we will not clobber its existing value.

}
