-The on-disk index ("payload") is a text file.
-The first 3 lines are header information containing CurrentVersion,
-the value of GOMODCACHE, and the validity date of the index.
-(This is when the code started building the index.)
-Following the header are sections of lines, one section for each
-import path. These sections are sorted by package name.
-The first line of each section, marked by a leading :, contains
-the package name, the import path, the name of the directory relative
-to GOMODCACHE, and its semantic version.
-The rest of each section consists of one line per exported symbol.
-The lines are sorted by the symbol's name and contain the name,
-an indication of its lexical type (C, T, V, F), and if it is the
-name of a function, information about the signature.
-
-The fields in the section header lines are separated by commas, and
-in the unlikely event this would be confusing, the csv package is used
-to write (and read) them.
-
-In the lines containing exported names, C=const, V=var, T=type, F=func.
-If it is a func, the next field is the number of returned values,
-followed by pairs consisting of formal parameter names and types.
-All these fields are separated by spaces. Any spaces in a type
-(e.g., chan struct{}) are replaced by $s on the disk. The $s are
-turned back into spaces when read.
-
-Here is an index header (the comments are not part of the index):
-0                                      // version (of the index format)
-/usr/local/google/home/pjw/go/pkg/mod  // GOMODCACHE
-2024-09-11 18:55:09                    // validity date of the index
-
-Here is an index section:
-:yaml,gopkg.in/yaml.v1,gopkg.in/yaml.v1@v1.0.0-20140924161607-9f9df34309c0,v1.0.0-20140924161607-9f9df34309c0
-Getter T
-Marshal F 2 in interface{}
-Setter T
-Unmarshal F 1 in []byte out interface{}
-
-The package name is yaml, the import path is gopkg.in/yaml.v1.
-Getter and Setter are types, and Marshal and Unmarshal are functions.
-The latter returns one value and has two arguments, 'in' and 'out'
-whose types are []byte and interface{}.
