+# INTRO:
+#	 This file contains several functions related to mp3 file's operations.
+#	 I wrote them in order to ease the process of transforming the encoding 
+#	 of mp3 file's id3tag from gbk to utf8. YOU NEED id3v2 to make these 
+#	 functions work.
+#    !!! USE THESE FUNCTIONS IN UTF-8 LOCALE !!!
+
+# TODO: 
+#	1. make all the functions work both on a directory and a file
+#	2. add testing feature to all functions
+#      * rename_delete_ending_artist()
+#      * check_artist()
+#	3. set_artist() maybe need to be improved
+#   4. if functions are called without params, echo "usage"
+
+# USAGE:
+#	1. source this file before use
+
+
+# get_title_1() can be used to get v1 title from an mp3 file's id3tag
+# get_title_1_convernted() convert its encoding from gbk to utf8
+

+	| sed -e 's/^Title  : //g' -e 's/[[:space:]]*Artist: [[:print:]]*//g' \
+	| iconv -f gbk -t utf8

+#            function ideally, because "." can't match invisible/unmappd char?
