This command will include 'file' as if it was part of the original script. Note that if a file is included in another directory, the current directory is still where the script was compiled from (not where the included file resides). If the compiler can't find the file it will look for it in every include directory. See !addincludedir for more information.
\c !include WinMessages.nsh
\c !include Library.nsh
\c !include MyConfig.nsh
\c !include ..\MyConfig.nsh
\S1{addincludedir} !addincludedir
\c directory
Adds another include directory to the include directories list. This list is searched when !include is used. This list's initial value is $\{NSISDIR\}\\Include alone.
\c !addincludedir ..\include
\c !include something.nsh
\S1{addplugindir} !addplugindir
\c directory
Causes the NSIS compiler to scan the given directory for Plugin DLLs.
\c !addplugindir myplugin
\c MyPlugin::SomeFunction
\S1{cd} !cd
\c new_path
This command will change the compiler to the new directory, new_path. new_path can be relative or absolute.
\c !cd ..\more-scripts\new
\S1{echo} !echo
\c message
This command will echo a message to the user compiling the script.
\c !echo "hello world"
\S1{error} !error
\c [message]
This command will issue an error to the script compiler and will stop execution of the script. You can also add a message to this error.
\c !ifdef VERSION & NOVERSION
\c !error "both VERSION and NOVERSION are defined"

On POSIX platforms, !execute will use system() just like \R{system}{!system}.
\c !execute '"%WINDIR%\notepad.exe" "${NSISDIR}\license.txt"'
\S1{packhdr} !packhdr
\c tempfile command
This option makes the compiler use an external EXE packer (such as \W{http://www.un4seen.com/petite/}{Petite} or \W{http://upx.sourceforge.net/}{UPX}) to compress the executable header. Specify a temporary file name (such as "temp.dat") and a command line (such as "C:\\program files\\upx\\upx -9 temp.dat") to compress the header.
\c !packhdr "%TEMP%\exehead.tmp" '"C:\Program Files\UPX\upx.exe" "%TEMP%\exehead.tmp"'
\S1{system} !system
\c command [compare comparevalue]
This command will execute 'command' using a call to system(), and if the return value compared (using 'compare') to 'comparevalue' is false, execution will halt. 'compare' can be '<' or '>' or '<>' or '='.
\c !system '"%WINDIR%\notepad.exe" "${NSISDIR}\license.txt"'

This command will issue a warning to the script compiler. You can also add a message to this warning.

Passing push will cause !verbose to push the current verbosity level on a special stack. Passing pop will cause !verbose to pop the current verbosity level from the same stack and use it.
\c !verbose push

\c !include WinMessages.nsh

\S0{comppredefines} Predefines
You can use these standard predefines to automatically add the build time to the title of development versions, add the date to the version number, etc.
