1. Introduction to verbose logging control
This library script is for inclusion in other programs and allows sophisticated logging and program debugging through use of a virtual console concept.
Please note. This document is a work in progress. There are advanced features that need usage examples. This is posted early to make REBOL users aware of this powerful logging utility. 06-May-2007
2. vprint At a Glance
>> von/tags [one] == none >> vprint/tags "This gets displayed, the tagging symbol matches" [one] This gets displayed, the tagging symbol matches == none >> vprint/tags "This isn't displayed, the tagging does not match current logging tag" [two] == none
The v in vprint, may be thought of as both verbose and virtual.
3. Using %vprint.r
Including these tools is simple. Just DO it.
or to execute this right out of the rebol.org library
