- This program reads a file containing function prototypes
- (like syscall_solaris.go) and generates system call bodies.
- The prototypes are marked by lines beginning with "//sys"
- and read like func declarations if //sys is replaced by func, but:
-	* The parameter lists must give a name for each argument.
-	  This includes return parameters.
-	* The parameter lists must give a type for each argument:
-	  the (x, y, z int) shorthand is not allowed.
-	* If the return parameter is an error number, it must be named err.
-	* If go func name needs to be different than its libc name,
-	* or the function is not in libc, name could be specified
-	* at the end, after "=" sign, like
-	  //sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt

-// 		sampleList    = sampleRange (',' sampleRange)* (',' ('…'|'...'))?
-// 		sampleRange   = decimalValue ('~' decimalValue)?
-// 		decimalValue  = value ('.' value)?
-//
-//		Symbol	Value
-//		n	absolute value of the source number (integer and decimals).
-//		i	integer digits of n.
-//		v	number of visible fraction digits in n, with trailing zeros.
-//		w	number of visible fraction digits in n, without trailing zeros.
-//		f	visible fractional digits in n, with trailing zeros.
-//		t	visible fractional digits in n, without trailing zeros.
-//
-// The algorithm for which the data is generated is based on the following
-// observations
-//
-//    - the number of different sets of numbers which the plural rules use to
-//      test inclusion is limited,
-//    - most numbers that are tested on are < 100
-//
-// This allows us to define a bitmap for each number < 100 where a bit i
-// indicates whether this number is included in some defined set i.
-// The function matchPlural in plural.go defines how we can subsequently use
-// this data to determine inclusion.
-//
-// There are a few languages for which this doesn't work. For one Italian and
-// Azerbaijan, which both test against numbers > 100 for ordinals and Breton,
-// which considers whether numbers are multiples of hundreds. The model here
-// could be extended to handle Italian and Azerbaijan fairly easily (by
-// considering the numbers 100, 200, 300, ..., 800, 900 in addition to the first
-// 100), but for now it seems easier to just hard-code these cases.

-    - if the first letter of the 2- and 3-letter ISO codes are the same:
-      the second and third letter of the 3-letter ISO code.
-    - otherwise: a 0 and a by 2 bits right-shifted index into altLangISO3.
-For 3-byte language identifiers the 4th byte is 0.`,
-	`
-langNoIndex is a bit vector of all 3-letter language codes that are not used as an index
-in lookup tables. The language ids for these language codes are derived directly
-from the letters and are not consecutive.`,
-	`
-altLangISO3 holds an alphabetically sorted list of 3-letter language code alternatives
-to 2-letter language codes that cannot be derived using the method described above.
-Each 3-letter code is followed by its 1-byte langID.`,

-altLangIndex is used to convert indexes in altLangISO3 to langIDs.`,

-AliasMap maps langIDs to their suggested replacements.`,
-	`
-script is an alphabetically sorted list of ISO 15924 codes. The index
-of the script in the string, divided by 4, is the internal scriptID.`,

-isoRegionOffset needs to be added to the index of regionISO to obtain the regionID
-for 2-letter ISO codes. (The first isoRegionOffset regionIDs are reserved for
-the UN.M49 codes used for groups.)`,
-	`
-regionISO holds a list of alphabetically sorted 2-letter ISO region codes.
-Each 2-letter codes is followed by two bytes with the following meaning:
-    - [A-Z}{2}: the first letter of the 2-letter code plus these two
-                letters form the 3-letter ISO code.
-    - 0, n:     index into altRegionISO3.`,
-	`
-regionTypes defines the status of a region for various standards.`,
-	`
-m49 maps regionIDs to UN.M49 codes. The first isoRegionOffset entries are
-codes indicating collections of regions.`,
-	`
-m49Index gives indexes into fromM49 based on the three most significant bits
-of a 10-bit UN.M49 code. To search an UN.M49 code in fromM49, search in
-   fromM49[m49Index[msb39(code)]:m49Index[msb3(code)+1]]
-for an entry where the first 7 bits match the 7 lsb of the UN.M49 code.
-The region code is stored in the 9 lsb of the indexed value.`,
-	`
-fromM49 contains entries to map UN.M49 codes to regions. See m49Index for details.`,
-	`
-altRegionISO3 holds a list of 3-letter region codes that cannot be
-mapped to 2-letter codes using the default algorithm. This is a short list.`,
-	`
-altRegionIDs holds a list of regionIDs the positions of which match those
-of the 3-letter ISO codes in altRegionISO3.`,
-	`
-variantNumSpecialized is the number of specialized variants in variants.`,
-	`
-suppressScript is an index from langID to the dominant script for that language,
-if it exists.  If a script is given, it should be suppressed from the language tag.`,
-	`
-likelyLang is a lookup table, indexed by langID, for the most likely
-scripts and regions given incomplete information. If more entries exist for a
-given language, region and script are the index and size respectively
-of the list in likelyLangList.`,
-	`
-likelyLangList holds lists info associated with likelyLang.`,
-	`
-likelyRegion is a lookup table, indexed by regionID, for the most likely
-languages and scripts given incomplete information. If more entries exist
-for a given regionID, lang and script are the index and size respectively
-of the list in likelyRegionList.
-TODO: exclude containers and user-definable regions from the list.`,

-regionInclusion maps region identifiers to sets of regions in regionInclusionBits,
-where each set holds all groupings that are directly connected in a region

-	`
-regionInclusionBits is an array of bit vectors where every vector represents
-a set of region groupings.  These sets are used to compute the distance
-between two regions for the purpose of language matching.`,
