+4.1 Runtime options
+===================
+
+Besides the configure- and compile-time options described in the
+installation section (*note Installation::), you can control a number of
+parameters in the 'texmf.cnf' runtime file read by Kpathsea (*note
+(kpathsea)Config files::).
+
+ The main purpose of 'texmf.cnf' is to specify search paths, but array
+sizes and other options are also set there. Most are rather obscure.
+Here are a few of the more interesting values:
+
+'main_memory'
+ Total words of memory available, for TeX, Metafont, and MetaPost.
+ Must remake the format file after changing.
+
+'extra_mem_bot'
+ Extra space for "large" TeX data structures (default 0): boxes,
+ glue, breakpoints, et al. If you use PiCTeX, you may well want to
+ set this.
+
+'expand_depth'
+ Limit on recursive expansion calls before TeX aborts (default
+ 10000). If a TeX program does an unterminated recursive expansion,
+ TeX will dutifully expand macros until the system's runtime stack
+ overflows, typically with a segmentation fault (SIGSEGV). This
+ parameter was introduced to minimize the chance of that unpleasant
+ (though not dangerous) crash, instead allowing TeX to quit with a
+ more informative message.
+
+ The crash can still happen, though, if the system has an
+ exceptionally small memory allocation for its stack. There is no
+ quantitative way to determine the limit, and it does not seem worth
+ implementing system-dependent heuristics to guess at the number,
+ since it's highly improbable that any real TeX code will ever need
+ more than 10000 recursive expansions (it has never happened). For
+ the same reason, using the libsigsegv library
+ (<https://gnu.org/s/libsigsegv>) does not seem worth the effort.
+
+'texmf_casefold_search'
+ *Note (kpathsea)Casefolding search::.
+
+ Ideally all arrays would be dynamically expanded as necessary, so the
+only limiting factor would be the amount of swap space available, or
+some configurable limit much larger than can currently be supported.
+
+ Unfortunately, implementing this is extremely difficult, as the fixed
+size of arrays is assumed in many places throughout the source code.
+These runtime limits are a practical compromise between the compile-time
+limits in previous versions, and truly dynamic arrays. (On the other
+hand, the Web2c BibTeX implementation does do true dynamic reallocation
+of some arrays.)
+
+ Nowadays there is rarely a reason to modify the values. But if you
+do wish to modify 'texmf.cnf', in TeX Live the best approach is to put
+your changes, and only your changes at the top of the TL installation
+tree. That is, if the system 'texmf.cnf' is installed in
+'/some/path/to/texlive/YYYY/texmf-dist/web2c/texmf.cnf' is put your
+custom settings in '/some/path/to/texlive/YYY/texmf.cnf', where YYYY is
+the year of installation (if you use that subdirectory; it's the
+default). That way, unrelated changes to the system 'texmf.cnf' can
+happen with normal updates, without affecting your local values.
