 #### Repository Names

-Repository names must be case-insensitive-unique but are CASE-SENSITIVE ON CASE-SENSITIVE FILESYSTEMS.  The name must be composed of letters, digits, or `/ _ - . ~`<br/>

+Repository names must be case-insensitive-unique but are CASE-SENSITIVE ON CASE-SENSITIVE FILESYSTEMS.  The name must be composed of letters, digits, or `/ _ - . ~ +`<br/>

 Whitespace is illegal.

 

 Repositories can be grouped within subfolders.  e.g. *libraries/mycoollib.git* and *libraries/myotherlib.git*
