+# This is a Makefile to generate the PO files for automated
+# translation. If you get through the trouble of creating PO file for
+# your language, you will save a lot of hassles with editing plain html
+# and repeated text, which also implies potential mistakes.
+
+# Please read the manual on the page:
+# http://dev.man-online.org/man7/po4a/
+
+# This Makefile only contains commands from the manual tested for the
+# esd translation.
+
+# After the translation of the PO file has been finished, generate new
+# files using: make -f Makefile.gen
+
+# flags for the po4a-getextize
+PO4A_FLAGS=-M utf-8 -f xhtml
+# list of source files for the translation

+# initialise the po template from English version, this is to be used,
+# there is no translation for now, and you are going to build it from
+# scratch. Then copy the file esd-temp.pot to your language file
+# esd-$(lang).po such as esd-cs.po, and edit it in your favourite PO
+# editor (such as poedit, or emacs with po-mode).
+
+# If you already have an old translation you can convert it to PO
+# files as described bellow.
+esd-temp.pot: $(foreach f,$(SRC),en/$f)

+# Convert existing translations into PO files.
+
+# NOTE: You need to make sure that your translated document is formaly
+# correct xhtml (there might be accidental mistakes).
+# Validate your document to find errors (e.g. https://validator.w3.org)
+
+# IMPORTANT: when you generate the PO files from the existing
+# translation, the original files in the version *corresponding* to
+# the translation have to be provided as a command line argument (with
+# parameter -m).
+
+# for that specify the directory where the original files are placed
+DIR=en
+# and the list of files that were translated within the corresponding
+# version
+FILES=$(SRC)
+
+# The generation of the PO file is likely to go wrong, because of the
+# mistakes which were introduced by the direct translation of the html
+# files. In this case the po4a gives quite good error message with a
+# reference in which file and line number to look at to find the
+# mistake. Go to that file and try to correct the errors and then
+# repeat the procedure.
+
+# Don't give it up translating PO files is nicer.
+
+# For more details and troubleshooting see:
+# http://dev.man-online.org/man7/po4a/
+# in section: HOWTO convert a pre-existing translation to po4a?
