Example: adding a TTSSH menu under File menu

    #define ID_SSHSCPMENU       52110

## What to do when new macro command is added?

- Coding
  - get a new number of command internal ID.
    ... teraterm/ttmacro/ttmparse.h
  - add a if statement to below function.
    ... CheckReservedWord@teraterm/ttmacro/ttmparse.c
  - add a caller doing the macro command.
    ... ExecCmnd@teraterm/ttmacro/ttl.c
  - make a function code for the macro command.
- Help topic
  - make the command help file.
    ... doc/LANG/html/macro/command/hogefunc.html
  - add the file to help topic.
    ... doc/LANG/teraterm.hhc
  - get a new number of context ID in help page.
    The value is internal ID + 92000.
    ... teraterm/common/helpid.h
  - make the alias between context ID and calling file.
    Open the .hhp file by using Text Editor, added a html line in [ALIAS] tag.
    ... doc/LANG/teraterm.hhp

On VS2008 Express Edition, following error occurs:
.\ttxssh.rc(10) : fatal error RC1015: cannot open include file 'afxres.h'.
To avoid this error, edit ttxssh.rc file. Delete the line of "afxres.h", and add 2 lines.

    - #include "afxres.h"
    + #include
    + #define IDC_STATIC -1

1. Checkout TTSSH source code from OSDN(https://osdn.net/projects/ttssh2/).

To release Tera Term installation package is shown in the following step:

### From start release until create RC

1. Confirm ticket and branches.
   - Confirm in project team.
     - Organize / decide whether to include bug fix / feature in this release or defer.
   - Merge branches
     - Verify trunk / 4-stable and working branches.
   - Close tickets.
2. Confirm tools, libraries, import sources.
   - Visual Studio (https://visualstudio.microsoft.com/)
   - Inno Setup (https://jrsoftware.org/isdl.php)
   - Oniguruma (https://github.com/kkos/oniguruma/)

   - The reference C implementation of Argon2 (https://github.com/P-H-C/phc-winner-argon2/)

### From create RC until release

1. Confirm documents.
2. Increment the version while RC release process.

   The binary is released for test in this timing. Prevent that old and new binary have same version number.

   - teraterm\common\tt-version.h
   - ttssh2\ttxssh\ttxssh-version.h
   - Onttpmenu\ttpmenu.rc // only modifying
   - TTProxy\TTProxy.rc // only modifying
   - TTXKanjiMenu\ttxkanjimenu.rc // only modifying

   By way of exception, CygTerm+ always upgrades not regarding Tera Term release process when the patch is committed.
   The release date is the day committed by a developer.
   Because user can get gcc compiler for free.

3. Increment the year of last publication of copyright notice if it is first release in this year.
