+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= README Release 1 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+This distribution contains release 2 of a copy of the 3.62 test release of
+GNU Make which has been modified to run under the emx 32-bit environment under
+MS-DOS or OS/2 2.0. (See the README.GNU file in either of the zoo files for
+more information about GNU Make.)
+
+GNU Make is free software. See the file COPYING for copying conditions. This
+program is provided with absolutely NO WARRANTY of any kind.
+
+The documentation for GNU make is provided in the from of .info files which
+have been created from the .texinfo files supplied in the original GNU
+release. To browse these files you will need a copy of GNU info which is
+probably available from the same source where you obtained this file.
+The documentation is compressed in the info.zoo file.
+
+The source code for this port of GNU make is also included in the source.zoo
+file.
+
+In porting GNU make I have taken a mostly slash and burn approach. GNU Make
+relies very heavily on the un*x fork function which is resource intensive.
+I have made massive changes in the job.c file so that this release does not
+use the fork function. This makes for a smaller executable and hopefully a
+program which is a little more robust in the emx environment.
+
+I have also changed the handling of commands within make. To illustrate the
+changes, imaging that make wants to issue a command:
+ gcc -c test.c
+First, it examines the command name (in this case "gcc"). If the name ends
+with a .bat, .cmd, or .com extension, make uses the emx system() function to
+ask either command.com or cmd.exe to execute the command. If the name does
+not end with a .bat, .cmd, or .com extension, make adds a ".exe" extension
+and looks for the command using the PATH environment variable. If it finds
+the command, it executes it directly via a spawnve() function call without
+loading command.com or cmd.exe. If the command contains any pipes (|) or
+output or input re-routing (<, >>, >) the system() function will be used to
+make sure that the operating system is allowed to handle these functions.
+
+This is done mostly to circumvent weaknesses in the emx environment under
+MS-DOS. Notably, when forced to use the system() function to under MS-DOS,
+make is unable to obtain the return code from the command and instead must
+assume that the command was completed successfully.
+
+Also, If a command line is more than ~100 characters long, this port of make
+will create a temporary response file and call the command with the response
+file, thus, creating a shorter command line. This could cause trouble if
+you try to call a program which does not understand how to handle response
+files with a large command line.
+
+I will gladly accept any question, comments, or insults for poor porting.
