Read a property file, sort the remainder alphabetically and write their values to
|
|
a text file, one value per line.
|
|
|
|
The idea is that this file could be translated and the result could be used to
|
|
create a new property file with property_inserter.rb
|
|
|
|
On the command line provide the path to the properties file. E.g.:
|
|
|
|
property_stripper.rb '../../all.properties' output_file
|
|
|
