Doing Summation On Multiple Criterias On The Same Column In A Singlequery

Hi all
I need to perform a summation on a column of a table based on a
criteria given in another column in the same table. The catch is i
need to perform different sums according to the number of criterias in
the criteria column, in a single query. the structure of the table is
somethinmg like this (only relevant columns are shown)

TABLE1
Value - numeric(20,6)
Month - int
indicator - bit

Now i need to do something like:

SELECT Month, SUM(Value) FROM TABLE1
WHERE indicator = 1
GROUP BY Month

and also

SELECT Month, SUM(Value) FROM TABLE1
WHERE indicator = 0
GROUP BY Month


How can i do this in a single query, something like this:
SELECT Month, SUM(Value where indicator=1), SUM(Value where
indicator=0) and so on .......

Could any body please help me on this ?
