Translators: This is the description of command line option '-u, --user-prefs'
that allows you to specify an alternate location from which to load the user
preferences.

Translators: This string indicates to the user what should be provided when
using the '-u, --user-prefs' command line option.

Translators: This is the description of command line option '--debug-file'
which allows the user to override the default date-based name of the debugging
output file.

Translators: This string indicates to the user what should be provided when
using the '--debug-file' command line option.

Translators: This is the description of command line option '--debug' which
causes debugging output for Orca to be sent to a file. The YYYY-MM-DD-HH:MM:SS
portion of the string indicates the file name will be formed from the current
date and time with 'debug' in front and '.out' at the end. The 'debug' and
'.out' portions of this string should not be translated (i.e. it should always
start with 'debug' and end with '.out', regardless of the locale.).

Translators: This message is displayed when the user starts Orca from the
command line and includes an invalid option or argument. After the message,
the list of invalid items, as typed by the user, is displayed.

Translators: This message is presented to the user who attempts
to launch Orca from some other environment than the graphical
desktop.

Translators: This message is presented to the user when the specified profile
could not be loaded. A profile stores a group of Orca settings configured for
a particular purpose, such as a Spanish profile which would include Spanish
braille and Spanish text-to-speech. The string substituted in is the user-
provided profile name.

Translators: This message is presented to the user when
he/she tries to launch Orca, but Orca is already running.

Translators: this is a regular expression that is intended to match
a positive 'yes' response from a user at the command line.  The expression
as given means - does it begin with (that's the '^' character) any of
the characters in the '[' ']'?  In this case, we've chosen 'Y', 'y', and
'1' to mean positive answers, so any string beginning with 'Y', 'y', or
'1' will match.  For an example of translation, assume your language has
the words 'posolutely' and 'absitively' as common words that mean the
equivalent of 'yes'.  You might make the expression match the upper and
lower case forms: "^[aApP1]".  If the 'yes' and 'no' words for your
locale begin with the same character, the regular expression should be
modified to use words.  For example: "^(yes|Yes)" (note the change from
using '[' and ']' to '(' and ')').

Finally, this expression should match what you've chosen for the
translation of the "Enter y or n:" strings for this file.
