copy

Generate a permuted index with automatically generated index references

$ ptx --auto-reference [path/to/file]
copy

Generate a permuted index with a fixed width

$ ptx --width=[width_in_columns] [path/to/file]
copy

Generate a permuted index with a list of filtered words

$ ptx --only-file=[path/to/filter] [path/to/file]
copy

Generate a permuted index with SYSV-style behaviors
