+VARIABLES
+ These variables control if the wildcards jokers and brackets must
+ capture their match. They can be globally set by writing in your program
+
+ $Regexp::Wildcards::CaptureAny = -1;
+ # From then, '*' jokers are capturing
+
+ or can be locally specified via "local"
+
+ {
+ local $Regexp::Wildcards::CaptureAny = -1;
+ # In this block, the '*' joker is capturing.
+ ...
+ }
+ # Back to the situation from before the block
+
+ This section describes also how those elements are translated by the
+ functions.
+
+ $CaptureSingle
+ When this variable is true, each occurence of the unescaped "?" joker is
+ made capturing in the resulting regexp (they are be replaced by "(.)").
+ Otherwise, they are just replaced by ".". Default is the latter.
+
+ 'a???b\\??' is translated to 'a(.)(.)(.)b\\?(.)' if $CaptureSingle is true
+ 'a...b\\?.' otherwise (default)
+
+ $CaptureAny
+ By default this variable is false, and successions of unescaped "*"
+ jokers are replaced by one single ".*". When it evalutes to true, those
+ sequences of "*" are made into one capture, which is greedy ("(.*)") for
+ "$CaptureAny > 0" and otherwise non-greedy ("(.*?)").
+
+ 'a***b\\**' is translated to 'a.*b\\*.*' if $CaptureAny is false (default)
+ 'a(.*)b\\*(.*)' if $CaptureAny > 0
+ 'a(.*?)b\\*(.*?)' otherwise
+
+ $CaptureBrackets
+ If this variable is set to true, valid brackets constructs are made into
+ "( | )" captures, and otherwise they are replaced by non-capturing
+ alternations ("(?: | ")), which is the default.
+
+ 'a{b\\},\\{c}' is translated to 'a(b\\}|\\{c)' if $CaptureBrackets is true
+ 'a(?:b\\}|\\{c)' otherwise (default)
