Main purpose of the script is easy support of Japanese typesetting
engines in TeXworks. As TeXworks typesetting setup does not allow
for multistep processing, this script runs one of the ptex based
programs (ptex, uptex, eptex, euptex, platex, uplatex) followed
by dvipdfmx.

INSTALLATION = [[
Copy the file ptex2pdf.lua into a directory where scripts are found,
that is for example

  `TLROOT/texmf-dist/scripts/ptex2pdf/`

(where `TLROOT` is for example the root of your TeX Live installation)

### Unix ###

create a link in one of the bin dirs to the above file, in the
TeX Live case:

  `TLROOT/bin/ARCH/ptex2pdf -> ../../texmf-dist/scripts/ptex2pdf/ptex2pdf.lua`

### Windows ###
create a copy of runscript.exe as ptex2pdf.exe, in the TeX Live case:

  `copy TLROOT/bin/win32/runscript.exe TLROOT/bin/win32/ptex2pdf.exe`
]]

TEXWORKS = [[
Under Preferences > Typesetting add new entries, for example:

for ptex files:

| Setting     | Value              |
|-------------|--------------------|
| Name:       | pTeX (ptex2pdf)    |
| Program:    | ptex2pdf           |
| Arguments:  | -ot                |
|             | $synctexoption     |
|             | $fullname          |

for platex files:

| Setting     | Value              |
|-------------|--------------------|
| Name:       | pLaTeX (ptex2pdf)  |
| Program:    | ptex2pdf           |
| Arguments:  | -l                 |
|             | -ot                |
|             | $synctexoption     |
|             | $fullname          |

for uptex files:

| Setting     | Value              |
|-------------|--------------------|
| Name:       | upTeX (ptex2pdf)   |
| Program:    | ptex2pdf           |
| Arguments:  | -u                 |
|             | -ot                |
|             | $synctexoption     |
|             | $fullname          |

for uplatex files:

| Setting     | Value              |
|-------------|--------------------|
| Name:       | upLaTeX (ptex2pdf) |
| Program:    | ptex2pdf           |
| Arguments:  | -l                 |
|             | -u                 |
|             | -ot                |
|             | $synctexoption     |
|             | $fullname          |

If you need special kanji encodings for one of these programs,
add the respective `-kanji` option with the `$synctexoption`. Example:

for platex files in SJIS encoding:

| Setting     | Value                      |
|-------------|----------------------------|
| Name:       | pLaTeX/SJIS (ptex2pdf)     |
| Program:    | ptex2pdf                   |
| Arguments:  | -l                         |
|             | -ot                        |
|             | -kanji=sjis $synctexoption |
|             | $fullname                  |
