| Vesrion history: |
| |
| 1.0 - Initial CCR release |
| |
| Release information for automatic CCR updates: |
| |
| BEGIN RELEASE NOTES: (signifies what gets put into CCR release notes) |
| 1.1 |
| - Entry points for va_list style msgs; new shell_imp_vmsg() |
| and shell_imp_verrmsg() |
| - shell_imp_env_checker() is now shell_imp_var_checker(). |
| Also the var_checker callback gets passed interp. |
| 1.2 - interposition framework (used by jdbx) |
| - access to input FILE pointer. |
| |
| END RELEASE NOTES: (signifies what gets put into CCR release notes) |
| |
| Following is used as a CCR version number: |
