Script to aid on a "reverse translation" FROM [a portuguese codebase with no i18n] TO [an english one with i18n]
# Script to aid on a "reverse translation":
# * FROM a portuguese codebase with no i18n
# * TO an english one with i18n
#
# Process:
#
# In the cenario wher your have all your code with portuguese strings and no i18n
# (Naturally that applies to other languages as well)
#
# 1. Mark all your translatable portuguese strings with gettext marks _(...)
# 2. generate a temporary .po file and save it as version "pt"
# 3. translate to english inplace (that means in the files itself)
# 4. generate another temporary .po file and save it as version "en"
# 5. call translate(...) to generate the final .po file from the previous two
