2016-03-17 Yesterday, mullers asked for groff macros to create letters in DIN 5008 format. [0] I mentioned my `brief' macros for troff. Those were created without knowledge of DIN 5008. An adjustment to that standard would be great. Today, mullers reported that he now found groff macros which solve this problem. [1] They could inspire the adjustment of my macros. When I wanted to find out which license applies to libtiff, I discovered that the license in the free software directory of the FSF [2] is wrong. Thus, I wrote a message, suggesting a correc- tion. [3] To solve a problem, I investigated into the memory management of the Java VM. Most helpful were these two sources.
