樫村さま
竹広です. 修正提案ありがとうございます.
1,2,3 を採り入れることは問題ないと思いますが, 4,5,6 はちょっと
悩んでいます. gp* シリーズで扱う変数の指定は gtool4 規約での
URL 記法に従う, ということが基本ですので, その方針を変更して
実装するのを躊躇しています.
http://www.gfd-dennou.org/library/gtool4/gt4ncconv/gt4ncconv_current/format.html
一方で, gtool4 規約を含みつつ拡張解釈するのであれば実装としては
問題ないのかなとも思います. このあたり, 識者のご意見を頂ければ
ありがたいです.
