+".SH NAME\r\n"
+"Starts a loop based on 'for' syntax.\r\n"
+".SH SYNOPSIS\r\n"
+" \r\n"
+"FOR %indexvar IN set\r\n"
+" command [arguments]\r\n"
+" [command [arguments]]\r\n"
+" ...\r\n"
+"ENDFOR\r\n"
+" \r\n"

+" [command [arguments]]\r\n"
+" ...\r\n"

+".SH OPTIONS\r\n"
+" \r\n"
+" %indexvar - Variable name used to index a set\r\n"
+" set - Set to be searched\r\n"
+" command [arguments] - Command to be executed with optional arguments\r\n"
+".SH DESCRIPTION\r\n"
+" \r\n"
+"NOTES:\r\n"
+" 1. The FOR command executes one or more commands for each item in a set of\r\n"
+" items. The set may be text strings or filenames or a mixture of both,\r\n"
+" separated by spaces (if not in a quotation).\r\n"
+" 2. If the length of an element in the set is between 0 and 256, and if the\r\n"
+" string contains wildcards, the string will be treated as a file name\r\n"
+" containing wildcards, and be expanded before command is executed.\r\n"
+" 3. If after expansion no such files are found, the literal string itself is\r\n"
+" kept. %indexvar is any alphabet character from 'a' to 'z' or 'A' to 'Z',\r\n"
+" and they are case sensitive. It should not be a digit (0-9) because\r\n"
+" %digit will be interpreted as a positional argument on the command line\r\n"
+" that launches the script. The namespace for index variables is separate\r\n"
+" from that for environment variables, so if %indexvar has the same name as\r\n"
+" an existing environment variable, the environment variable will remain\r\n"
+" unchanged by the FOR loop.\r\n"
+" 4. Each command is executed once for each item in the set, with any\r\n"
+" occurrence of %indexvar in the command replacing with the current item.\r\n"
+" In the second format of FOR ... ENDFOR statement, %indexvar will be\r\n"
+" assigned a value from start to end with an interval of step. Start and\r\n"
+" end can be any integer whose length is less than 7 digits excluding sign,\r\n"
+" and it can also applied to step with one exception of zero. Step is\r\n"
+" optional, if step is not specified it will be automatically determined by\r\n"
+" following rule:\r\n"
+" if start <= end then step = 1, otherwise step = -1.\r\n"
+" start, end and step are divided by space.\r\n"
+".SH EXAMPLES\r\n"
+" \r\n"
+"EXAMPLES:\r\n"
+" * Sample FOR loop - listing all .txt files:\r\n"
+" echo -off\r\n"
+" for %a in *.txt\r\n"
+" echo %a exists\r\n"
+" endfor\r\n"
+" \r\n"
+" # \r\n"
+" # If in current directory, there are 2 files named file1.txt and file2.txt\r\n"
+" # then the output of the sample script will be as shown below.\r\n"
+" # \r\n"
+" Sample1> echo -off\r\n"
+" file1.txt exists\r\n"
+" file2.txt exists\r\n"
+" \r\n"
+" * Theoretically it is legal for 2 nested FOR commands to use the same\r\n"
+" alphabet letter as their index variable, for instance, a: \r\n"
+" #\r\n"
+" # Sample FOR loop from 1 to 3 with step 1\r\n"
+" #\r\n"
+" echo -off\r\n"
+" for %a run (1 3)\r\n"
+" echo %a\r\n"
+" endfor\r\n"
+" \r\n"
+" #\r\n"
+" # Sample FOR loop from 3 down to 1 with step -1\r\n"
+" #\r\n"
+" echo -off\r\n"
+" for %a run (3 1 -1)\r\n"
+" echo %a\r\n"
+" endfor\r\n"
+" \r\n"
+" #\r\n"
+" # Sample FOR loop - 2 nested for using same index variable\r\n"
+" #\r\n"
+" echo -off\r\n"
+" for %a in value1 value2\r\n"
+" for %a in value3 value4\r\n"
+" echo %a\r\n"
+" endfor\r\n"
+" endfor\r\n"
+" \r\n"
+" Note: When processing first FOR and before seeing the ENDFOR, the index\r\n"
+" variable %a has the value "value1", so in second FOR, the %a has\r\n"
+" been already defined and it will be replaced with the current value\r\n"
+" of %a. The string after substitution becomes FOR value1 in value3\r\n"
+" value4, which is not a legal FOR command. Thus only when the value\r\n"
+" of %a is also a single alphabet letter, the script will be executed\r\n"
+" without error. If 2 independent FOR commands use the same index\r\n"
+" variable, when the second FOR is encountered, the first FOR has\r\n"
+" already freed the variable so there will be no problem in this case.\r\n"

+" end of the file is reached, the search resumes at the top of the file and\r\n"
+" continues until label is found or the starting point is reached. If label\r\n"
+" is not found, the script process terminates and an error message is\r\n"
+" displayed. If a label is encountered but there is no GOTO command\r\n"

+".SH DESCRIPTION\r\n"
+" \r\n"
+"NOTES:\r\n"
+" 1. The IF command executes one or more commands before the ELSE or ENDIF\r\n"
+" commands, if the specified condition is TRUE; otherwise commands between\r\n"
+" ELSE (if present) and ENDIF are executed.\r\n"
+" 2. In the first usage of IF, the EXIST condition is true when the file\r\n"
+" specified by filename exists. The filename argument may include device\r\n"
+" and path information. Also wildcard expansion is supported by this form.\r\n"
+" If more than one file matches the wildcard pattern, the condition\r\n"
+" evaluates to TRUE.\r\n"
+" 3. In the second usage, the string1 == string2 condition is TRUE if the two\r\n"
+" strings are identical. Here the comparison can be case sensitive or\r\n"
+" insensitive, it depends on the optional switch /i. If /i is specified,\r\n"
+" it will compare strings in the case insensitive manner; otherwise, it\r\n"
+" compares strings in the case sensitive manner.\r\n"
+" 4. In the third usage, general purpose comparison is supported using\r\n"
+" expressions optionally separated by AND or OR. Since < and > are used for\r\n"
+" redirection, the expressions use common two character (FORTRAN)\r\n"
+" abbreviations for the operators (augmented with unsigned equivalents):\r\n"
+" - Expressions : Conditional expressions are evaluated strictly from left\r\n"
+" to right. Complex conditionals requiring precedence may\r\n"
+" be implemented as nested IFs.\r\n"
+" The expressions used in the third usage can have the\r\n"
+" following syntax:\r\n"
+" conditional-expression := expression |\r\n"
+" expression and expression |\r\n"
+" expression or expression\r\n"
+" expression := expr | not expr\r\n"
+" expr := item binop item | boolfunc(string)\r\n"
+" item := mapfunc(string) | string\r\n"
+" mapfunc := efierror | pierror | oemerror\r\n"
+" boolfunc := isint | exists | available | profile\r\n"
+" binop := gt | lt | eq | ne | ge | le | == | ugt | ult |\r\n"
+" uge | ule\r\n"
+" - Comparisons : By default, comparisons are done numerically if the\r\n"
+" strings on both sides of the operator are numbers\r\n"
+" (as defined below) and in case sensitive character sort\r\n"
+" order otherwise. Spaces separate the operators from\r\n"
+" operands.\r\n"
+" 5. The /s option forces string comparisons and the /i option forces\r\n"
+" case-insensitive string comparisons. If either of these is used, the\r\n"
+" signed or unsigned versions of the operators have the same results.\r\n"
+" The /s and /i apply to the entire line and must appear at the start of\r\n"
+" the line (just after the if itself). The two may appear in either order.\r\n"
+" 6. When performing comparisons, the Unicode Byte Ordering Character is\r\n"
+" ignored at the beginning of any argument.\r\n"
+" 7. Comparison Operator Definition:\r\n"
+" gt : Greater than\r\n"
+" ugt : Unsigned Greater than\r\n"
+" lt : Less than\r\n"
+" ult : Unsigned Less than\r\n"
+" ge : Greater than or equal\r\n"
+" uge : Unsigned greater than or equal\r\n"
+" le : Less than or equal\r\n"
+" ule : Unsigned less than or equal\r\n"
+" ne : Not equal\r\n"
+" eq : Equals (semantically equivalent to ==)\r\n"
+" == : Equals (semantically equivalent to eq)\r\n"
+" 8. Error Mapping Functions are used to convert integers into UEFI, PI or OEM\r\n"
+" error codes.\r\n"
+" Functions used to convert integers into UEFI, PI or OEM error codes:\r\n"
+" UefiError : Sets top nibble of parameter to 1000 binary (0x8)\r\n"
+" PiError : Sets top nibble of parameter to 1010 binary (0xA)\r\n"
+" OemError : Sets top nibble of parameter to 1100 binary (0xC)\r\n"
+" Each function maps the small positive parameter into its equivalent error\r\n"
+" classification.\r\n"
+" For example:\r\n"
+" if %lasterror% == EfiError(8) then # Check for write protect.\r\n"
+" ...\r\n"
+" 9. Boolean Functions may only be used to modify operators in comparisons.\r\n"
+" The following built-in Boolean functions are also available:\r\n"
+" IsInt : Evaluates to true if the parameter string that follows\r\n"
+" is a number (as defined below) and false otherwise.\r\n"
+" Exists : Evaluates to true if the file specified by string exists\r\n"
+" is in the current working directory or false if not.\r\n"
+" Available : Evaluates to true if the file specified by string is in the\r\n"
+" current working directory or current path.\r\n"
+" Profile : Determines whether the parameter string matches one of the\r\n"
+" profile names in the profiles environment variable.\r\n"
+" 10. No spaces are allowed between function names and the open parenthesis,\r\n"
+" between the open parenthesis and the string or between the string and\r\n"
+" the closed parenthesis. Constant strings containing spaces must be\r\n"
+" quoted.\r\n"
+" 11. To avoid ambiguity and current or future incompatibility, users are\r\n"
+" strongly encouraged to surround constant strings that contain\r\n"
+" parenthesis with quotes in if statements.\r\n"
+" 12. Allowable number formats are decimal numbers and C-style case\r\n"
+" insensitive hexadecimal numbers. Numbers may be preceded by a\r\n"
+" "-" indicating a negative number.\r\n"
+" Examples:\r\n"
+" 13\r\n"
+" 46\r\n"
+" -0x3FFF\r\n"
+" 0x3fff\r\n"
+" 0x1234\r\n"
+" 13. Unsigned values must be less than 264. Signed integer values are bounded\r\n"
+" by -/+263.\r\n"
+" 14. Numbers are internally represented in two's compliment form. The\r\n"
+" representation of the number in the string has no bearing on the way\r\n"
+" that number is treated in an numeric expression - type is assigned by\r\n"
+" the operator. So, for example, -1 lt 2 is true but -1 ult 2 is false.\r\n"
+" 15. The IF command is only available in scripts.\r\n"
+" 16. The ELSE command is optional in an IF/ELSE statement.\r\n"
+".SH EXAMPLES\r\n"
+" \r\n"
+"EXAMPLES:\r\n"
+" * Sample script for "if" command usages 1 and 2:\r\n"
+" if exist fs0:\myscript.nsh then\r\n"
+" myscript myarg1 myarg2\r\n"

+" myscript1\r\n"
+" myscript2\r\n"
+" else\r\n"
+" echo ^%myvar^% != runboth\r\n"
+" endif\r\n"
+" Note: In this example, if the script file myscript.nsh exists in fs0:\,\r\n"
+" this script will be launched with 2 arguments, myarg1 and myarg2.\r\n"
+" After that, environment variable %myvar% is checked to see if its\r\n"
+" value is runboth, if so, script myscript1 and myscript2 will be\r\n"
+" executed one after the other, otherwise a message %myvar% != runboth\r\n"
+" is printed.\r\n"
+" \r\n"
+" * Sample script for "if" command usage 3:\r\n"
+" :Redo\r\n"
+" echo Enter 0-6 or q to quit\r\n"
+" # assumes "input y" stores a character of user input into variable y\r\n"

+" endif\r\n"
+" if /i %MyVar% ne q then\r\n"
+" echo Invalid input\r\n"
+" goto Redo\r\n"
