`transform nudged_static` takes named parameters in the form of `gensfen param_1_name param_1_value param_2_name param_2_value ...` and flag parameters which don't require values. `transform nudged_static` takes named parameters in the form of `transform nudged_static param_1_name param_1_value param_2_name param_2_value ...` and flag parameters which don't require values.
This command goes through positions in the input files and replaces the scores with new ones - generated from static eval - but slightly adjusted based on the scores in the original input file.

`relative` - states that the adjustment should be bounded by a value relative in magnitude to the static eval value. After this token follows the maximum relative change - a floating point value greater than 0. For example a value of 0.1 only allows changing the static eval by at most 10% towards the score from the input file. `relative` - states that the adjustment should be bounded by a value relative in magnitude to the static eval value.

## `rescore_fen`
`transform rescore_fen` takes named parameters in the form of `transform rescore_fen param_1_name param_1_value param_2_name param_2_value ...` and flag parameters which don't require values.
This command takes a path to the input file which contains one FEN per line and outputs a .bin or .binpack file with these positions rescored with specified depth search.
Currently the following options are available:
`input_file` - path to the input .epd file. Default: in.binpack.
`output_file` - path to the output .bin or .binpack file. The file is opened in append mode. Default: out.binpack.
`depth` - the search depth to use for rescoring. Default: 3.
