# Special thanks to Hilário Leal Fontes and Maria José Machado, who helped to test the script and made very helpful suggestions

# ***Purpose***: Create a copy of your trained corpora that can be used by someone else (even if in another computer) or by you yourself in a different Moses installation (you can have more than one Moses installation in the same computer). Your $mosesdir is written literally (e.g., "/home/john") in several trained corpora files. You have to change that string so that it reflects the $mosesdir to which you want to transfer your trainings. This script locates your $mosesdir string in your trained corpora files and substitutes it by the equivalent $mosesdir string that defines the location where you want your trainings transferred to. It creates a $mosesdir/corpora_trained_for_another_location/newusername directory, within which it will create the corpora_trained and logs directory prepared for the other user/Moses installation. Takes a good while to run if you have trained very large corpora.

# THIS SCRIPT ASSUMES THAT A IRSTLM AND RANDLM ENABLED MOSES HAS ALREADY BEEN INSTALLED WITH THE create script IN $mosesdir; ITS  #
# DEFAULT VALUE IS $HOME/moses-irstlm-randlm; CHANGE THIS VARIABLE IF YOU WANT IT TO REFER TO A DIFFERENT LOCATION.                        #
# IT ALSO ASSUMES THAT THE TRAINING OF A CORPUS HAS ALREADY BEEN DONE WITH train-moses-irstlm-randlm.                                      #
