See https://github.com/acejump/AceJump/issues/348 for information on what's changed and what more needs to be done.

-#   Gradle start up script for POSIX generated by Gradle.
+##  Gradle start up script for UN*X
-#
+##
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.

+ * Solves the Tag Assignment Problem. The tag assignment problem can be stated
+ * thusly: Given a set of indices I in document d, and a set of tags T, find a
+ * bijection f: T*⊂T → I*⊂I s.t. d[i..k] + t ∉ d[i'..(k + |t|)], ∀ i' ∈ I\{i},
+ * ∀ k ∈ (i, |d|-|t|], where t ∈ T, i ∈ I. Maximize |I*|. This can be relaxed
+ * to t=t[0] and ∀ k ∈ (i, i+K] for some fixed K, in most natural documents.
+ *
+ * More concretely, tags are typically two-character strings containing alpha-
+ * numeric symbols. Documents are plaintext files. Indices are produced by a
+ * search query of length N, i.e. the preceding N characters of every index i in
+ * document d are identical. For characters proceeding d[i], all bets are off.
+ * We can assume that P(d[i]|d[i-1]) has some structure for d~D. Ultimately, we
+ * want a fast algorithm which maximizes the number of tagged document indices.
+ *
+ * Tags are used by the typist to select indices within a document. To select an
+ * index, the typist starts by activating AceJump and searching for a character.
+ * As soon as the first character is received, we begin to scan the document for
+ * matching locations and assign as many valid tags as possible. When subsequent
+ * characters are received, we refine the search results to match either:
+ *
+ *    1.) The plaintext query alone, or
+ *    2.) The concatenation of plaintext query and partial tag
+ *
+ * The constraint in paragraph no. 1 tries to impose the following criteria:
+ *
+ *    1.) All valid key sequences will lead to a unique location in the document
+ *    2.) All indices in the document will be reachable by a short key sequence
+ *
+ * If there is an insufficient number of two-character tags to cover every index
+ * (which typically occurs when the user searches for a common character within
+ * a long document), then we attempt to maximize the number of tags assigned to
+ * document indices. The key is, all tags must be assigned as soon as possible,
+ * i.e. as soon as the first character is received or whenever the user ceases
+ * typing (at the very latest). Once assigned, a visible tag must never change
+ * at any time during the selection process, so as not to confuse the user.
