 ## THE TOOLS
 
+Many tools have a ` z88dk-` prefix to distinguish them from tools from other packages that may be installed with the same name. The documentation
+generally omits the prefix when referring to them.
+
 * **ZCC** is the toolchain's front end.  zcc can generate an output binary out of any set of input source files.
 * **SCCZ80** is z88dk's native c compiler.   sccz80 is derived from small c but has seen much development to the point that it is nearly c90 compliant.
 * **ZSDCC** is z88dk's customization of the [sdcc compiler](https://github.com/z88dk/sdcc).  Our patch makes sdcc compatible with the z88dk toolchain, gives it access to z88dk's extensive assembly language libraries and ready-made crts, addresses some of sdcc's code generation bugs and improves on sdcc's generated code.
 * **Z80ASM** (not to be confused with several external projects called z80asm) is a fully featured assembler / linker / librarian implementing sections.
 * **Z80NM** is z80asm's companion archiver.  It can provide a listing of functions or data encoded in an object or library file.
 * **APPMAKE** processes the raw binaries generated by the toolkit into a form suitable for specific target machines.  For example, it can generate intel hex files, tapes, ROMs, etc.
-* **TICKS** is a command line z80 emulator that can be used to time execution speed of code fragments. Ticks includes a debugger and disassembler in addition to supporting some of the ZX Next extension instructions.
+* **Z88DK-TICKS** is a command line z80 emulator that can be used to time execution speed of code fragments. Ticks includes a debugger and disassembler in addition to supporting some of the ZX Next extension instructions.
 * **Z88DK-DIS** is a command line disassembler for Z80, Z180, ZXN and Rabbit 2000/3000. It can additionally read map files generated by z80asm to provide a more symbolic output.
 * **Z88DK-LIB** is an installer for third party libraries.  It manages installation, removal and listing of available libraries.
-* **ZX7** is a PC-side optimal lz77 data compression tool with companion decompression functions in the z80 library.
-* **DZX7** is a PC-side decompressor counterpart to zx7.
+* **Z88DK-ZX7** is a PC-side optimal lz77 data compression tool with companion decompression functions in the z80 library.
+* **Z88DK-DZX7** is a PC-side decompressor counterpart to zx7.
 
 These tools are not normally directly invoked by the user:
 
 * **M4** acts as z88dk's macro preprocessor and can optionally process files ahead of the c preprocessor or assembler.
-* **UCPP** is the c preprocessor invoked for sccz80.
+* **Z88DK-UCPP** is the c preprocessor invoked for sccz80.
 * **ZSDCPP** is the c preprocessor invoked for zsdcc.
-* **ZPRAGMA** is used by the toolchain to process pragmas embedded in c source.
-* **COPT** is a regular expression engine that is used as peephole optimizer for sccz80 and as a post-processing tool for both sccz80 and zsdcc.
+* **Z88DK-ZPRAGMA** is used by the toolchain to process pragmas embedded in c source.
+* **Z88DK-COPT** is a regular expression engine that is used as peephole optimizer for sccz80 and as a post-processing tool for both sccz80 and zsdcc.
