How to set the SVN username for shared work areas?

Problem

I would like to set the SVN username to something other than the login name for use with shared work areas.

Solution

The  'VSC_SVN_USERNAME' variable sets the username to use:

;;;----------------------------------------------------------------------------
;;; Define VSC_SVN_USERNAME to run svn commands as a different user than the
;;; current login - this is useful when sharing a workarea
;;;
;;;
;;; VSC_SVN_USERNAME: Dynamic
;;;----------------------------------------------------------------------------
;; VSC_SVN_USERNAME = "alice"

'VSC_SVN_USERNAME' can be set in the 'versic.conf' file located under the path specified by the 'VSC_CONFIG_DIR' environment variable, but will normally be set as an environment variable.
