Programs using this library should define `char *argv0` and set it to
the 0:th command line argument.

+libsimple include a number of functions complementing those in <string.h>
+and <strings.h>, the naming scheme of these functions is:
+
+ <base> = str for NUL-terminated byte strings
+ = strn for byte strings that may not be NUL-terminated
+ = mem for byte arrays
+ = wcs for NUL-terminated wide-character strings
+ = wcsn for wide-character strings that may not be NUL-terminated
+ = wmem for wide-character arrays
+
+ <str> = str if <base> is str, wsc, strn, or wscn
+ = mem if <base> is mem or wmem
+
+ <scan> = chrnul if <base> is str, wsc, strn, or wscn
+ = scan if <base> is mem or wmem
+
+ [case] = if case-sensitive
+ = case if case-insensitive, the name may also end with
+ _l if there is a locale parameter
+
+ [_inv] = for normal search
+ = _inv for search of anything else (skipping)
+
+ [r] = for left-to-right search/comparison
+ = r for right-to-left search/comparison
+
+ [p] = return beginning of destination
+ = p return end of destination
+
+ [raw] = sought data may not exist
+ = raw sought data does exist (only <base> = mem, wmem)
+
+ <base>[r] = strrn if <base> is strn
+ = wcsrn if <base> is wcsn
+ = <base>r otherwise
+
+ <base>[p] = stp if <base> is str
+ = stpn if <base> is strn
+ = wcp if <base> is wcs
+ = wcpn if <base> is wcsn
+ = <base>p otherwise
+
+ [raw]<base>[r][case]chr[_inv] find character
+ <base>[case]<scan>[_inv] find character or end
+ <base>[r][case]<str> find substring
+ <base>[case]cmp alphabetically compare, without NULL support
+ <base>[case]cmpnul alphabetically compare, with NULL support
+ <base>[case]ends verify end
+ <base>[case]starts verify beginning
+ <base>[case]eq !<base>[case]cmp
+ <base>[case]eqnul !<base>[case]cmpnul
+ <base>[r][case]eqlen check length of commonality
+ <base>end find end of string (not <base> = mem, wmem)
+ <base>[p]cpy copy data (to external array)
+ <base>[p]move move data (within array or to external array)
+ <base>[p]set fill data
+ <base>[p]toupper like <base>[p]move but convert text to upper case
+ <base>[p]tolower like <base>[p]move but convert text to lower case
+ [raw]<base>ccpy like <base>pcpy, but stop after a character is found
+ [raw]<base>cmove like <base>pmove, but stop after a character is found
+ <base>replace replace all instance of a character, end is returned
+ mem[p]setelem fill data with elements of custom length
+ [raw]mem[r]elem[_inv] find element with custom length
+ memelemscan[_inv] find element with custom length or end
+ memreplaceelem replace all instance of an element of custom length, end is returned
