(This page has never contained anything, please use the [Regular Expressions] page instead - [LV])

(But note that [Regular Expressions] will take you to a place where Tcl's [ARE] are discussed, and there are other [RE] flavors around - [Luciano ES])

----
Okay then - feel free to add information here on the other RE flavors
available in Tcl...

[LES] says that there no other RE flavors available in Tcl. Tcl only uses [ARE]. What I meant is that Regular Expressions may be construed as any one (or all) of its several variations, but [Regular Expressions] only discusses Tcl's [ARE]. I said that because this wiki discusses many things under several contexts, not necessarily that of [Tcl], and I thought it would be good to note that in this case '''it is''' restricted to the context of Tcl.
