This function will parse and process a line of text is if read from a
technology file. It can therefor modify parameters that are otherwise
set in the technology file, after a technology file has been read, or
if no technology file was read.
However, there are limitations.
- There is no macro processing done on the line, it is parsed
verbatim, and macro directives will not be understood.
- There is no line continuation, all related text must appear in
the given string.
- The print driver block keywords are not recognized, nor are any
other block forms, such as device blocks for extraction.
- Layer block keywords are acceptable, however they must be given
in a special format, which is
[elec]layer layername layer_block_line...
i.e., the text must be prefaced by the layer/eleclayer
keyword followed by an existing layer name. Note that new layers must
be created first, before calling this function.
If the line is recognized and successfully processed, the function
returns 1. Otherwise, 0 is returned, and a message is available from
