Microsoft (R) .NET Resource Generator 
[Microsoft .Net Framework, Version {0}]
{1}

Usage:
   ResGen inputFile.ext [outputFile.ext] [/str:lang[,namespace[,class[,file]]]]
   ResGen [options] /compile inputFile1.ext[,outputFile1.resources] [...]

Where .ext is .resX, .restext, .txt, or .resources

Converts files from one resource format to another.  If the output
filename is not specified, inputFile.resources will be used.
Options:
/compile        Converts a list of resource files from one format to another
                in one bulk operation.  By default, it converts into .resources
                files, using inputFile[i].resources for the output file name.
/str:[,[,[,]]]] 
                Creates a strongly-typed resource class in the specified
                programming language using CodeDOM. In order for the strongly
                typed resource class to work properly, the name of your output 
                file without the .resources must match the
                [namespace.]classname of your strongly typed resource class.
                You may need to rename your output file before using it or
                embedding it into an assembly. 
/useSourcePath  Use each source file's directory as the current directory
                for resolving relative file paths.
/publicClass    Create the strongly typed resource class as a public class.
                This option is ignored if the /str: option is not used.
/r:   Load types from these assemblies. A ResX file with a previous
                version of a type will use the one in this assembly, when set.
/define:A[,B]   For #ifdef support in .ResText files, pass a comma-separated
                list of symbols.  ResText files can use "#ifdef A" or "#if !B".

Miscellaneous:
@         Read response file for more options. At most one response file
                may be specified, and its entries must be line-separated.

.restext  .txt files have this format:

    # Use # at the beginning of a line for a comment character.
    name=value
    more elaborate name=value

Example response file contents: 

    # Use # at the beginning of a line for a comment character.
    /useSourcePath
    /compile
    file1.resx,file1.resources
    file2.resx,file2.resources
