/* Generate-C-Converted-Lisp-Source
6
/* convert a lisp source code into C which is interpretedly
7
/* executed by Euslisp when it is compiled (by cc) and linked.
8
/* Though some lisp source programs, e.g. l/constants.l, must be
9
/* loaded during the make procedure, it is hard to locate the
10
/* file since no file handling functions are available.
11
/* Genlispexec converts "constants.l" into "constants.l.c"
12
/* which should be compiled by 'cc'. The resulted "constants.l.o"
13
/* may be linked with eus, which then interprets the same program
14
/* as defined in "constants.l".
