 ## Paste parallel files together
 
 This script reads one line at a time from a set of files and concatenates them with a triple pipe separator (`|||`) in the output. This is useful for generating parallel corpora files for training or evaluation:

 ## Punctuation Normalization and Tokenization
 
 This script tokenizes text in any language (well, it does a good job in most languages, and in some it will completely go crazy):
+
     ./tokenize-anything.sh < input.txt > output.txt
 
 It also normalizes a lot of unicode symbols and even corrects some common encoding errors. It can be applied to monolingual and parallel corpora directly.

 ## Text lowercasing
 
 This script also does what it says, provided your input is in UTF8:
+
     ./lowercase.pl < input.txt > output.txt
 
 ## Length ratio filtering (for parallel corpora)
 
 This script computes statistics about sentence length ratios in a parallel corpus and removes sentences that are statistical outliers. This tends to remove extremely poorly aligned sentence pairs or sentence pairs that would otherwise be difficult to align:
+
     ./filter-length.pl input.src-trg > output.src-trg
 
 ## Add infrequent self-transaltions to a parallel corpus
 
 This script identifies rare words (those that occur less than 2 times in the corpus) and which have the same orthographic form in both the source and target language. Several copies of these words are then inserted at the end of the corpus that is written, which improves alignment quality.

     ./add-self-translations.pl input.src-trg > output.src-trg
