Regular Expression

Hi All,
This regular expression is in awk.
What does this regular expression evaluate to(character by character).

($0 ~ /^ .+*([0-9]|-).+*\*+.?*\*/)

^ is beginning of line
space is just itself
.+ is any character, one or more times
([0-9]|-) matches either a single digit or a dash
.+ is any character, one or more times
* in this context is a syntax error, but otherwise specifies a repetition of zero or more times
\*+ is one or more literal asterisks
.? matches zero or one occurrence of any character
* in this context is again a syntax error
\* is a literal asterisk
