Merging lines in a file

Hi,

I want to merge the lines starting with a comma symbol with the previous line of the file.

Input :

cat file.txt

name1,name2
,name3,name4
emp1,emp2,emp3
,emp4
,emp5
user1,user2
,user3

Output

name1,name2,name3,name4
emp1,emp2,emp3,emp4,emp5
user1,user2,user3

IS there any command in unix to do this conversion for the entire file?

Mohan
