=head1 NAME

F<epgsearchuservars.conf> - User defined variables

=head1 DESCRIPTION

In this file you can defines variables which then can be used
in epgsearch in any play where variables are possible.

=head1 SYNTAX

Variables looks like %Variablename%.

"Variablename" can be consist of any alphanumerical character. Space
and special characters are not allowed.

The variable names are case-insensitive.

Examples for possible names:

 %Series% %DocuVar1% %ThemesSubtitleDate1%

=head2 Assignment

 %Series%=New series~Thriller

The variable %Series% will be assigned with the string "New series~Thriller".

Assignments are always strings. Spaces stay spaces.

 %Path%=%Series%

The variable %Path% gets the content of the variable %Series%.

You can do nearly everything:

 %Path%=%Serie%~Lost

The variable %Path% contains now the string "New series~Thriller~Lost".

=head2 Control structures

You can use simple "if then else" constructions.

These constructions cannot contain strings, only variables.
Spaces are ignored.

 %Foo%=Other

 %Variable%=%Path% ? %Path% : %Foo%

If %Path% is not empty, assign the content of %Path% to %Variable%,
otherwise the content of %Foo%.

"%Path% ?" means "not empty?". You can use other checks.

 %Variable%=%Path%!=5 ? %Path% : %Foo%

"%Path%!=5 ?" means "is %Path% equal 5?"

You can also compare variables.

 %Five%=5

 %Variable%=%Path%!=%Five% ? %Path% : %Foo%

Other possible checks:

 ==   equal
 !=   not equal

=head2 Calling a system command

You can call external commands. The returned string will be assigned
to a variable

 %Result%=system(scriptname,%Variable1% %Variable2% -f %Variable3% --dir=%Variable4% --dummy)

Calls the script "scriptname" with the parameters "%Variable1%",
"%Variable2%", etc. The result will be stored in %Result%.

You can use as many variables as you want.

If needed, epgsearch will quote the variable.

The script must return a string B<without> line break!

If the script returns nothing, an empty string will be assigned to the
Variable %Result%.
