The Capitalize(s) command changes each word in the string s to its capitalized form.

A word is a maximal sequence of alphanumeric characters delimited by another character, or the beginning or end of the string.

The capitalized form of a string is the string obtained by replacing each alphabetic character that begins a word with the corresponding uppercase character, and replacing each non-leading alphabetic character in each word with the corresponding lowercase character. Characters that are not part of a word are not affected.

The CamelCase(s) command converts a string of concatenated words to camel case. The term camel case refers to the capitalization convention used when forming programming language identifiers from multiple words, in which the first letter of each constituent word is capitalized to aide readability. For example, LinearAlgebraicGroups is a camel case string, whereas linearalgebraicgroups and linear_algebraic_groups follow different conventions.

Sometimes, a string like linearAlgebraicGroups is also referred to as camel case, wherein only interior word starts are capitalized. This form of camel case can be obtained from the output of CamelCase by converting the first letter of the result to lowercase.
