+# Extracts all texts from the file i18n.c and creates language
+# specific *.po files.

+# Usage: i18n-to-gettext.pl
+#
+# See the main source file 'vdr.c' for copyright information and

+
+# How to convert an actual plugin:
+#
+# - If your code contains something like
+#
+# const char *Text = "Some text";
+# ...
+# Function(tr(Text));
+#
+# you need to enclose the text constant in trNOOP(...), as in
+#
+# const char *Text = trNOOP("Some text");
+#
+# The actual usage of the tr() macro remains unchanged.
+#
+# - If you have comments following the texts in your i18n.c file
+# that should be seen by the translators, move them from the
+# i18n.c file into the file where the text is actually used,
+# and mark them with the TRANSLATORS keyword, as in
+#
+# // TRANSLATORS: note the plural!
+# Add(new cMenuEditIntItem( tr("Setup.EPG$Preferred languages"), ...
+#
+# - Fill in your email address in the line
+# $MSGIDBUGS = "" ...
+# below, so that users can reach you in case there is a problem
+# with a message id.
+#
+# - Run this Perl script from within your plugin's source directory.
+# This script will run 'xgettext' to extract all of your texts
+# into a file named <pluginname>.pot. After that it will extract
+# your existing i18n texts from the file i18n.c (or wherever you
+# have defined them) and generate *.po files for all languages
+# currently known by VDR.
+#
+# - Your Makefile will be automatically adjusted to allow for
+# building the *.mo files necessary for supporting gettext().
+# Please check carefully whether the automatic adjustments have
+# succeeded, though.
+#
+# - You may want to remove the old internationalized texts from your
+# source. Usually this means removing the files i18n.[hc], stripping
+# i18n.o from the OBJS variable in the Makefile and removing all
+# '#include "i18n.h"' lines from the rest of your source files.
+# These steps are not done automatically.
+
+# Check for the existence of a Makefile:
+
+die "Makefile not found!" unless (-f "Makefile");
+
+# Determine the plugin name:
+
+$PLUGIN = `grep '^PLUGIN *=' Makefile | head -1` || die "can't find plugin name!";
+$PLUGIN =~ s/.*= *(.*)\n/$1/;
+die "can't find plugin name!" unless ($PLUGIN);
+
+# Locate the file containing the texts:
+
+$I18NFILE = "";
+for ("i18n.c", `ls *.c`) { # try i18n.c explicitly first
+ chomp($f = $_);
+ if (-f $f && `grep tI18nPhrase $f`) {
