ass2srt [option] .ass source files [.srt purpose of file]

    The Advanced SubStation Alpha ".ass" file format to SubRip ".srt" format.

  -d, --default=encoding  default = encoding set the default file encoding, which is the purpose of the source file and use the same code file.
                          The default value is UTF-8 encoding format.

  -f, --from=encoding    from = encoding specified source file. ass coding system used. The set will be covered by the aforementioned pre -
                           Coding based on the settings file, when not specified the default file encoding for the default value.
                         * Tip: You can also use the system environment variables specified ASS2SRT_FROM

  -t, --to=encoding       encoding file specified purposes. srt coding system used. The set will be covered by the aforementioned pre -
                           Coding based on the settings file, when not specified the default file encoding for the default value.

  -p, --preserve          preserve the source file to retain. ass subtitles in the control instructions, write together. srt file.

  -o, --dos               dos specified output file format for DOS (the default format for Unix)
                        * Warning: can not be set this option with -m/--mac together.

  -m, --mac               mac specify the output file format for the Mac (the default format for Unix)
                        * Warning: can not be this option with set -o/--dos together.

  --debug                 print debugging output for each line of the .ass file read.

  --nocorrect             don't attempt to correct errors in subtitles
                        if not specified, corrections will be made for the following errors:
                          - subtitle i+1 begins before subtitle i ends - subtitle i's end will be set to subtitle i+1's begin
                          - subtitle i+1 begins at the same time as subtitle i begins - subtitles will be merged into one subtitle

.ass source file:
    The Subtitles of the original file.
    It can be Advanced SubStation Alpha (.ass) or SubStation Alpha (.ssa) format.

[.srt purpose file]:
    The default SubRip format output filename, the default value is the same as 
    the .ass source filename but it's extension changed to .srt.

Operation Example:

  Like iconv utility, use -f to specified from encoding set, the -t to specified target encoding set.

   1. Convert a utf16-le.ass file encoded with Unicode/UTF-18 LE to big5.srt with Big5 encoding.

       myhost  \$ perl ass2srt.pl -f utf16-le -t big5 utf16-le.ass big5.srt

   2. Convert a Big5 encoding .ass file to UTF-8 encoding .srt file

       myhost  \$ perl ass2srt.pl -f big5 -t utf8 big5.ass utf8.srt

   3. Convert a UTF-8 encoding .ass file to UTF-8 encoding .srt file, 
      no -f or -t parameter because UTF-8 is the default encoding setting.

       myhost  \$ perl ass2srt.pl utf-8.ass utf-8.srt

   4. Convert a UCS-2 LE encoding .ass file to UCS-2 LE encoding .srt file,
      UCS-2 LE is the same as Unicode encoding on Windows Platform.

       myhost  \$ perl ass2srt.pl -f ucs-2le -t ucs-2le ucs-2le.ass ucs-2le.srt

   5. Using the environment variables to specified encoding parameter
      * Warning: Some operation system can not add " or ' quotation marks to the varialbe's value

       myhost  \$ export ASS2SRT_FROM = utf16-le
       myhost  \$ export ASS2SRT_TO = big5
       myhost  \$ perl ass2srt.pl utf16-le.ass big5.srt
