re­al­boxes – Vari­ants of com­mon box-com­mands that read their con­tent as real box and not as macro ar­gu­ment

The pack­age uses the au­thor's pack­age col­lect­box to de­fine vari­ants of com­mon box re­lated macros which read the con­tent as real box and not as macro ar­gu­ment. This en­ables the use of ver­ba­tim or other spe­cial ma­te­rial as part of this con­tent.
The pro­vided macros have the same names as the orig­i­nal ver­sions but start with an up­per-case let­ter in­stead. The "long-form" macros, like \Make­box, can also be used as en­vi­ron­ments, but not the "short-form" macros, like \Mbox. How­ever, nor­mally the long form uses the short form any­way when no op­tional ar­gu­ments are used.
