-=head1 NAME
-
-overlapping_regions.pl - calculates overlapping regions in the assembly table
-
-=head1 SYNOPSIS
-
-overlapping_regions.pl [arguments]
-
-Required arguments:
-
-  --host, --dbhost, --db_host=HOST    database host HOST
-  --port, --dbport, --db_port=PORT    database port PORT
-  --user, --dbuser, --db_user=USER    database username USER
-  --pass, --dbpass, --db_pass=PASS    database passwort PASS
-  
-  --pattern, --dbpattern=PATTERN      patch databases where name matches PATTERN
-                                      Note that this is a database pattern of
-                                      the form %core_41% rather than a regexp
- 
-Optional arguments:
-
-  -n, --dry, --dry_run                don't write results to database
-  -h, --help, -?                      print help (this message)
-
-Please note that where an argument expects a value, this is true for all
-alternative argument styles.
-
-=head1 DESCRIPTION
-
-This is a script that will calculate if an assembly has overlapping regions
-in same coordinate system (e.g. 2 chr_1 stored in the assembly table, one as
-the current, the other as an old version). It will store a new entry in the meta
-table. If there are overlapping regions, can cause problems when moving features
-between coordinate systems. The pattern is a string that can be used in an
-'IN' clause in SQL (e.g. "%_core_%"; if you want to patch only a single
-database, use a pattern without % expansion, e.g. "homo_sapiens_core_38_36").
-
-=head1 EXAMPLES
-
-   perl overlapping_regions.pl -host ens-staging -user ensadmin -pass xxxx
-        -pattern "%core_55_%" -port 3306 -dry_run 0
