LAYOUT -- relative locations of Macaulay 2 files

Description

The hash table LAYOUT is a translation table from symbolic names to directory paths, which are to interpreted relative to the path stored in prefixDirectory. Some of the entries are strings: these provide paths to various types of files associated with the main Macaulay 2 system. The remaining entries are functions. These provide paths to various types of files associated with packages, and accept a string containing the name of the package as argument. Finally, for convenience, many Macaulay 2 files are regarded as being associated with a special package called Core, and the corresponding documentation files are part of the package Macaulay2.

o1 = HashTable{bin => bin/                                           }

o1 : HashTable

Let's apply the functions above to the name of a fictional package named "FOO" to see what paths are returned.

i2 : applyValues (LAYOUT, f -> if instance(f,Function) then f "FOO" else f)
