CCR info
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:
