All technologies used in the library must be in the header. The other reason for a technology declaration to exist is if the technology has preferences stored on it. If there are multiple technology lines, they are sorted by technology name. The syntax is:

T<name> [ | <variable> ]*
<name> | the name of the technology.
<variable> | a list of preferences on the technology (stored as variables, see Section 10-4-1).

Examples:

`Tmocmos`
Declares that there should be a technology called "mocmos".

`Tmocmos|ScaleFORmocmos()D200`
Declares the technology "mocmos" and also creates a project setting on that technology object called "ScaleFORmocmos" which is a double-precision value equal to 200.
