| 49 | # a Tcl script that sets up package information with "package require" |

| 56 | # loaded when "package require" is executed, rather |

| 57 | # than lazily when the first reference to an exported |
---|
| 58 | # procedure in the package is made. |
---|
| 59 | # -verbose (optional) Verbose output; the name of each file that |
---|
| 60 | # was successfully rocessed is printed out. Additionally, |
---|
| 61 | # if processing of a file failed a message is printed. |
---|
| 62 | # -load pat (optional) Preload any packages whose names match |

---|
| 64 | # other packages during their Init procedure. |
