-This is sam (not including samterm) from the 4th edition of Plan 9,
-with changes so that it can be compiled under unix.
-(Tested on Solaris 7 and Debian 3.0r1.)
-
-Some extra libraries are needed.  First, fetch libutf-2.0 and libfmt-2.0
-from
-	http://pdos.lcs.mit.edu/~rsc/software/
-
-(Beware that in libfmt/fmt.c there is a line that says:
-        'u',    __ifmt,         /* in Plan 9, __flagfmt */
-Thus, sam will have to fmtinstall the other thing.  Other ported programs
-may have to do the same.  The fmt library should probably print messages
-about bad format characters to stderr, since no one seems to check the
-return codes.)
-
-Compile and install those two libraries.  
-Set PREFIX in the Makefile to match, then compile sam.
-
-Your C compiler will emit many complaints of the form:
-  sam.c:496: warning: passing arg 1 of `bufread' from incompatible pointer type
-
-This is because the Plan 9 compiler has a slightly different (better,
-ala Oberon) type system than ISO C.  Popular compilers generate the right
-code, so in an act of civil disobediance I changed just enough to get
-it to compile, but left the type errors in.  Now the next C standard can
-adopt this extension, because at least one important C program uses it!
