+This is a script used for query sigs infomation in openEuelr register in openeuler/community/sig/sigs.yaml 
+(1) This script depends on openuler/commnity/sig/sigs.yaml file,
+    suppose you clone commnuity and openEuler-Advisors in the same directory,
+    then you needn't specify the sigs.yaml path
+
+(2) Command parameters
+    -s Specify the sigs name,list the packages in the sigs
+       (eg:-s dev-utils)
+    -p Specify the packages name ,query the packages belong which sigs
+       (eg:-p mate-polkit )
+    -l List all sigs in openEuler
+    -y yaml:sigs.yaml path in community repository's location of you clone
+       default is ../../community/sig/sigs.yaml
