The leading period forces a command or script to run in the current
shell instead of in a subshell.  This is sometimes necessary,
especially where user defined functions or environment variables are
to be defined and used in the current shell as well as all of the
subshells run from within the current shell.  For example, running the
following command from the console:

/etc/bashrc

might not allow any variables or functions to be usable in the current
console, while the command:

. /etc/bashrc

will allow any changes in the /etc/bashrc file to be effective
immediately.

See the 'bash' man page for more details.

HTH, and have a _great_ day.
