This package provides macros to make the file I/O in plain TeX more transparent. That is, every \input, \openin, and \openout operation by TeX is presented to the user who must check carefully if the file name of the source is acceptable. The user must sometimes enter additional text and has to specify the file name that the TeX operation should use. The macros require a complex installation procedure; the package contains Sed and Bash scripts. Every installation is different from any other as password-protected macro names and private messages have to be chosen by the installer. Therefore, the files in the package cannot be used directly. For details see the manual.
